Cloudmin hangs when trying to go into Host System -> IP Addresses

Submitted by drtester on Sun, 02/19/2012 - 22:58

On a new Cloudmin install on Centos 6.2 X64 with KVM, when I click on HOST System - > IP Addresses, the browser hangs. Looking at the host, I see tons of webmin's server processes stacking up, and load starts skyrocketing. I stopped the browser before the host did something bad. This is reproducible 100% of the time.

What ip allocation range have you defined for your KVM hosts?

I can't tell, because I can't get in there to see. I'm not sure if anything was defined.

You should be able to see them at Host Systems -> KVM Host Systems -> your host.

BTW, are you running Cloudmin GPL or Pro?

I am running the GPL version. Ah, I see.. I had a large netblock in there of 8192 IPs. From what I recall, when I first installed, it did not seem to like my actual range (very small block), so I had to put a larger number in. I just put in a class C, and it still takes its time, but it does recover. I guess it is trying to ping every one? I think you might want to not do that if the range is large.

Yes, it attempts to ping all the IPs in your allocation range to see which ones are really free. This is done using 20 parallel processes, to reduce the ping time ... so it should be relatively fast for a class C, unless your system is low on memory.

I will fix Cloudmin in the next release to not attempt to ping large IP ranges (more than 1024 addresses), and add an option to turn off pinging completely.
