Perl Segmentation fault for server and user manipulation commands

After upgrade to webmin (1.791) I have this messages for various commands: list-users, changing quota etc.

I am on OVH VPS.

This is my shell commands how I reproduced problem:

Thanks for any relevant info or tips how to solve this issue.




Howdy -- it sounds like your Linux system is restricting what the processes running on it are allowed to do.

It looks like grsecurity may be responsible for at least some of that.

You may want to try disabling grsecurity, or configure it to ignore the Webmin processes.

Hello, thanks for reply. I have accidentally replied into ( but I have also tested several kernels from OVH (with distro kernel I was unable to use ETH driver) marked -std- and -grsec-.

GRSEC kernels stands for enabled security. STD without. I currently running the one:

root@webserver:~# uname -r

I also tried to mess up with various bootup settings without any luck.

Output remain the same:

root@webserver:~# virtualmin list-users --domain
Segmentation fault

All problems looks like related to users - I am unable to change quota, add user or create new virtual server :/

Any tips hove to revert back to normal?

I suppose that I am not only one running Webmin, Usermin on OVH VPS.

I have willingness to reinstall whole system to another VPS and migrate all domains (150+) to new system but without working user-lists and related function I am stuck :/

I have no problem to with to payed model for virtualmin or buy support package to solve this problem.

There likely isn't a simple way to get things working with grsecurity itself. So coming up with a way to disable grsecurity is the direction we'd suggest.

If you're open to using paid support, that does open up some options!

There's the option of switching to a Virtualmin Pro license, or purchasing a support incident. Or, if things are dire, you could actually hire us to migrate things to a new server for you.

We can definitely help out in that case; I'm not sure how yet, but we can figure something out.

I'm not sure which of those payment options to choose at the moment though, as this isn't an issue we've run into very often. Maybe you could hold off on buying one of those options until we have a better idea as to the problem?

I'd like to think that there is a way to switch kernels and have that work.

Can you describe what happens when switching to a standard kernel? You said you couldn't use the eth driver -- what was happening there exactly?

Hi, If my understands are correct OVH have some kind of pre-rebuild solution for their VMWare solution containing ethernet drivers.

My first experience with debian bundled kernel (though apt-get) was that everything started properly (postgres, nginx, etc.) but I was unable to do any connection inside or outside.

I will try at end of week (outside main times) some more kernels and I will let you know.

Just to verify, as I'm not fully certain I understand -- are the kernels you're trying now provided by OVH? Or are they Debian kernels, provided by the distro?


I am sorry for delayed response I have to concentrate to another project delivery.

To clarify your question:

I have tested following kernels from OVH (std - as without security and grs - with security) and also standard distro kernel.

Virtualmin was installed with OVH kernel and worked properly over 2 years. No (I do not know why) it does not work properly:

Looks that most of errors are related to user I am unable to list users of server where quota is enabled. But I am not able to change them when quota is reached. I am also unable to create new servers (in certain configurations) add users.

As I mentioned I have some spare budget for maintenance which I would like to spend for professional license of virtualmin or in this trouble case for support, because this error is out of my skills. Are you able to provide me some estimates of time/costs for help from your side?

No problem on the delay!

If we thought this was some sort of "normal" configuration issue, or a coding bug, we'd be more than happy to work with you on that, and to look deeper into that problem.

The kinds of problems you're seeing are really unusual though, and appear to be specific to the environment at your provider there. While there are folks using OVH who aren't experiencing that particular issue, I am wondering if the easiest solution isn't to just change providers (which I think you were mentioning as an option above, assuming you were able to run the appropriate commands to do so).

You mentioned that list-users isn't working. However, is the backup function working? Or does that error out too?

It really looks like there is some kind of security or resource restriction that is preventing things from working properly.

All that said, I do have a few questions for you just to rule out a handful of simpler things --

What kind of VPS do you have? For example, Xen, KVM, OpenVZ?

And what is the output of these two commands:

free -m
dmesg | tail -30

Oh, and this one might generate quite a bit of output, but I'm curious what it shows:

strace virtualmin list-users --domain

Thanks. Last command reveals most important stuff:

recvfrom(4, "7\0\0\1\377\36\4#42S22Unknown column 'use"..., 16384, 0, NULL, NULL) = 59

So I suppose that is related with my MySQL version 5.7 and changes related to user table - notable password field is missing. I have trie hot-fix to add password column into user table and copy passwords from authentication_string into password. But looks like nothing changed.

To your questions: - VPS Type - If I understand correctly from console when restarting there is VMWare solution. I would like to migrate inside OVH to OpenStack (there are allowed to connect additional HDD)

and finally:

strace virtualmin list-users --domain

is stored in external file (350 kB)

Segfaults mean that "something under the hood" is breaking. Something at the kernel level, or maybe a library.

Perl code can't cause a segfault. Instead, it indicates that something is very awry.

It shouldn't happen due to MySQL columns and such -- that would generate friendlier errors, as that's a more normal/expected kind of problem.

That MySQL activity in the strace output is most likely just normal activity that Virtualmin was performing when something else caused a problem.

That gave me an idea though.

What is the output of this command:

cat /etcsecurity/limits.conf

# /etc/security/limits.conf
#Each line describes a limit for a user in the form:
#<domain>        <type>  <item>  <value>
#<domain> can be:
#        - an user name
#        - a group name, with @group syntax
#        - the wildcard *, for default entry
#        - the wildcard %, can be also used with %group syntax,
#                 for maxlogin limit
#        - NOTE: group and wildcard limits are not applied to root.
#          To apply a limit to the root user, <domain> must be
#          the literal username root.
#<type> can have the two values:
#        - "soft" for enforcing the soft limits
#        - "hard" for enforcing hard limits
#<item> can be one of the following:
#        - core - limits the core file size (KB)
#        - data - max data size (KB)
#        - fsize - maximum filesize (KB)
#        - memlock - max locked-in-memory address space (KB)
#        - nofile - max number of open files
#        - rss - max resident set size (KB)
#        - stack - max stack size (KB)
#        - cpu - max CPU time (MIN)
#        - nproc - max number of processes
#        - as - address space limit (KB)
#        - maxlogins - max number of logins for this user
#        - maxsyslogins - max number of logins on the system
#        - priority - the priority to run user process with
#        - locks - max number of file locks the user can hold
#        - sigpending - max number of pending signals
#        - msgqueue - max memory used by POSIX message queues (bytes)
#        - nice - max nice priority allowed to raise to values: [-20, 19]
#        - rtprio - max realtime priority
#        - chroot - change root to directory (Debian-specific)
#<domain>      <type>  <item>         <value>

Try commenting out everything in your limtis.conf file, and see if there is a change after that.

If I comment mysql section I will be unable to run MySQL (known problem) and I am unable to do that with 100+ domains relied on this (maybe in the middle of night). Do you really believe that it might help?

Try increasing the MySQL section perhaps to 200000, and then comment out everything else.

You can always wait until after business hours to test that.

Okay... I'm unfortunately not quite sure what else to try there.

Have you tried talking to your provider about this issue?

It's possible they've heard about it before and would know what to do.

Other than that, the only other thought i have would be to attempt migrating elsewhere, either to another provider, or to another type of host at this provider.

The normal way to do that is using Virtualmin's backup functionality, though if that's not working properly that would be a problem.

The other way would be to stop all the services, and to rsync the various important files and directories (but not rsync'ing more than necessary, as you wouldn't want to accidentally copy over the cause of the problem). That wouldn't be easy, especially with 150+ sites, but if the backup functionality doesn't work that may be the only other way to get that up and running somewhere else.

I have to agree with Eric that there's a kernel issue happening here (it could also be underlying hardware; memory or disk corruption can lead to weird stuff like this that kinda spans a bunch of different services and tasks...though rebooting would likely change the symptoms). Nothing Webmin/Virtualmin does should even be able to cause a segfault (being written in high level languages without directly managing memory, Webmin doesn't have any control over this stuff), much less consistently trigger them for some tasks.

Am I understanding you correctly that you've tried booting into different kernels? Perhaps rolling back to one that worked in the past would be an option? If not, any solution will probably have to involve the OVH folks; kernel level segfaults are out of our reach...we can't fix them.

You could also try reducing memory usage on the system, to see if it leads to different behavior. If OVH are overselling memory, it might manifest this way (I don't know, as I haven't seen this particular behavior before, but some weird errors in the past have been due to oversold memory). So, you could turn off library caching in Webmin, reduce MySQL buffer sizes, get rid of unneeded Apache modules, etc. If the symptoms change or go away, you'd be able to guess that maybe that's the problem. Some VM hosting platforms are kinda notorious for memory problems (OpenVZ and Virtuozzo, in particular, as it is used so heavily by cut-rate hosts who oversell their systems heavily). OVH doesn't have a bad reputation, as far as I know, but it could still be a memory related issue, if they've misconfigured something.

Thanks for support, I will try reach OVH (we are under Czech branch which redirects requests to France) and we will see. I am going to keep you informed.

My assumption was correct. I am not Perl guy but syslog related outputs and malfunctioned MySQL module worried me.

Today I have googled more and found this

So I have changed nodbi=1 and everything works as expected.

Question is if this is really Webmin bug.

Oh, wow! I remember that issue now, but it's been years since anyone ran into it, so I didn't even think of it. I would think that would be a MySQL DBD bug. But, why it's hitting a new system is weird. I thought it was an old bug that had since been fixed. Does your system have a non-standard Perl or libraries from a source other than the OS repos?

Hi. It is now very confusing what caused what. During my journey to solve this problem I have tried almost everything - from Kernel switch, to install and trying to change gr security and of course CPAN manipulation :/

So I thing I am unable to answer with confidence :-)
