webmin + dovecot crashing all the time

psykolio · November 21, 2013, 2:33pm

Hello!
I’ve been experiencing some problems with a new installation of webmin/virtualmin on a new debian server (32Gb RAM, 2x2To hd, 3.4GHz CPU, Debian 7.2). Every 5/6 hours, the webmin process crashes. The errors I found in miniserv.error seem to be triggered by various processes (collectinfo.pl, webmincron.pl, spamconfig.pl, …) with
“double free or corruption”, or “smallbin double linked list corrupted” or “free(): invalid next size (fast)”

Sometimes dovecot is crashing and sometimes ssh is crashing too (making the server unreachable without hard rebooting).

Any advice would be greatly appreciated!

Howdy,

Hmm, that’s a pretty unusual issue.

It may be a sign of a deeper problem, though it’s difficult to say what exactly that might be.

It’s possible you’re seeing some sort of hardware problem.

It’s also possible that a library such as glibc is corrupted (that error is being thrown by glibc), or another library that those apps link to.

What distro/version are you using?

Thank you for your message!

I’m using Debian 7.2 (Wheezy). I found that when the problems begin to appear, I get some random segmentation faults on some processes (just had the issue with apt-get update).

And if I want everything to run normally, I have to reboot the server. After the reboot, everything seem to work for a few hours…

Eric · November 21, 2013, 5:18pm

The symptoms you’re describing almost sound like bad RAM.

The server uses the least amount of RAM when it first boots up, and then slowly expands to use all the RAM available to it.

If there were a RAM problem, that would explain why it worked okay for a period of time after a reboot.

Do you have a way of performing a RAM test?

-Eric
