Server memory crash

Distro Discussion & Help
1

I am currently using the latest version of FreePBX Distro and I am experiencing an issue on multiple, identical servers (with multiple clients) where the server software frequently crashes throughout the day and requires a hard reboot.

I have looked up this problem in the community and it seems to be related to a memory leak, the resolution being to upgrade/patch Asterisk.

I have two questions:

-How can I verify the crash is caused by a memory leak?
-If upgrading or patching Asterisk is the resolution, how do I successfully apply it for FreePBX Distro?

Thanks for any and all help.

What version of FreePBX Distro are you using ?
What version of asterisk are you using ?

As ggtest stated above, we would need more information that what was provided to really be able to assist you with your issues. However as for updating the distro, you can do so by using the FreePBX Distro upgrade scripts located at http://www.freepbx.org/forum/freepbx-distro/distro-discussion-help/stable-release-versions.

Thanks. I’ve never seen the Schmooze download section before, very nice. Especially the standalone installations.

I noticed this was a prevalent issue, should installing one of the stable editions solve this?

Also I have two production systems I am willing to open up to any developer willing to troubleshoot. Let me know if that is something of interest.

After a backup/restore and a reinstall using the full iso of Stable-1.812.210.57(Release Date-05/04/12) I am still experiencing crashes on two production systems.

Which is annoying, but I’m going to leave my emotions out of it.

Any ideas?

What emotion and at what are you annoyed?

If you provide more information I am sure you will get some support from the community.

I’d say I’m feeling a little frustration, a little resentment, and a little apprehension. Detailed enough?

Anyways.

Any developer from FreePBX: tell me what specs and/or log reports you’d like to detail this problem so I can resolve it.

I typed the sentence wrong, I did not mean emotion.

I was trying to get at what you are frustrated, the software, perceived lack of support etc.

Starting with the basics. What kind of machine? Have you tried something else? What is in /var/log/messages at the time of crash?

I suggest you read this:

Please keep in mind this is an isolated problem. We have been stepping up our distro conversions. Below please see my busiest system. It processes 1000 calls an hour, 250 extensions and it runs on a dual core AMD with 2G of RAM and doesn’t even break a sweat. This also should show you the state of a stable machine.
