Grandchild failed with exit status 127

Hey,

I've got this in my logs, could you please help ?

Jun 13 10:25:01 universe CRON[9700]: (CRON) error (grandchild #9703 failed with exit status 127)
Jun 13 10:26:01 universe CRON[9733]: (CRON) error (grandchild #9734 failed with exit status 127)
Jun 13 10:30:01 universe CRON[9846]: (CRON) error (grandchild #9848 failed with exit status 127)
Jun 13 10:30:01 universe CRON[9845]: (CRON) error (grandchild #9852 failed with exit status 1)
Jun 13 10:31:01 universe CRON[9880]: (CRON) error (grandchild #9881 failed with exit status 127)

It seems webmin is guilty :

crontab -l
1,6,11,16,21,26,31,36,41,46,51,56 * * * * /etc/webmin/virtual-server/collectinfo.pl
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /etc/webmin/status/monitor.pl

For your info :

uname -a

What happens if you run those commands from the command line as root?

You should be able to run "/etc/webmin/virtual-server/collectinfo.pl" and "/etc/webmin/status/monitor.pl" from the command line -- and what you should see, after a few moments, is it just going back to the command line.

Do you instead get any sort of error?

Also, you may want to take a look in /var/webmin/miniserv.error to see if any errors show up in there.

Hi,

well I can't run these scripts as they do not show up in the list of /etc/webmin files and directories :

And :

Hmm, well, that looks like a bit of a pickle... not having the "virtual-server" directory there means it doesn't think Virtualmin is installed at all.

When you access port 10000 on your server and log in, do you see Virtualmin? Or is it just Webmin?

Hum it seems it's just webmin...

I don't have any use of virtualmin... any way to get rid of this message ?

Thank you

Howdy,

Since you aren't using Virtualmin, you wouldn't need either of those cron jobs.

You could simply remove those from cron, and you should stop seeing those errors.

Great thanks.

HI,

in fact, problem is not solved. I still have these message even if I removed the lined and restarted cron.

Any idea ?

Fri, 07/01/2011 - 09:05
andreychek

Well, according to this here, the error code 127 is a "command not found" error:

http://tldp.org/LDP/abs/html/exitcodes.html

If you're still getting that error, there's likely other entries in your crontab that are calling programs that don't exist. You may need to review your cron entries and make sure the commands they're running exist.

Since you aren't using Virtualmin on your system -- if there's any other commands pointing to to something in the dir /etc/webmin/virtual-server/, you may want to be suspicious of those.

-Eric

Oh I see.

Well the error code changed since I removed the crontab entry, it's now a "code 1" error, which basically could mean anything.

My cron is now empty, by the way.

So strange !

Fri, 07/01/2011 - 12:52
andreychek

Well, it could be another users cron... there's also all the cron jobs in /etc/crontab and the directories /etc/cron*.

I'd look at the errors you're getting, and try and figure out what cron jobs they correspond with by the time they're running.

Hi Eric, thank you very much for your help.

Well indeed, there are so many files in /etc/cron*

I figured out that it seems to be this one, running every 10 minutes :

0,10,20,30,40,50 * * * * www-data [ -x /usr/lib/cgi-bin/awstats.pl -a -f /etc/awstats/awstats.conf -a -r /var/log/apache/access.log ] && /usr/lib/cgi-bin/awstats.pl -config=awstats -update >/dev/null

I tried

sudo apt-get remove awstats

but it just said awstats is not installed... Strange.

Anyway, I commented out the line, we'll see what it does...
