apache + php 5.2.12 child died with signal 6 or 11

Unread post by krho »

I'm having some trouble with apache crashes. And I get 3 different ones. All of them end in glibc. I'm using CentOS 5.3. So now I'm wondering has this something to do with the fact that PHP is probably? compiled on newer/older centos which has a bit different glibc?

Any thoughts?

Looks like you're using the itk version of apache, did you get that from atomic-testing?

Hi scott.

No the apache is from. http://redhat.sorbonne.fr/CentOS-5/sirisplus/i386/ repo.

Before that I also has some crashes with child died with signal 11, but the all ended in mod_jk. As only a couple of customers was using that I was able to disable it and thought that crashes are gone.. A few days later those started to appear. The problem with that is that after this happens somehow a couple of crashed apache processes stay alive or php is left in inconsistent state and if it happens that your request comes to that process you get a blank page with no error in any of the logs.

I can try replacing itk from sorbonne with the one from your testing repo... but I have everything but good memories of doing yum downgrade.
