We found apache crashing when user request the first side of one of our websides (seg. fault in logs). This happend with the upgrade from php 4.06 to 4.1.0 and is still happening with 4.1.1. Untill now I thought that this is probably a problem of the old apache version we are using, but then I expierienced some sort of wonder when accessing the page from my linux box from at home - and it worked 100%. So, if the page is accessed  using M$ Internet explorer (5-6), the apache child crashes by 70%, if accessed through mozilla, it doesn't. This is definitly out of my understanding and probably not fixable by changing the apache version...maybe anyone knows some sort of problem and can give me some hints?
I'm probably not able to do any sort of debugging if it means to recompile php or apache as I have to wait for maintanance in one-two weeks to shut down the system - and don't ask, there's no test server because of money reasons in a small company. I will do my best to provide anything else and would love to hear some suggestions for recompiling (what will probably happen on maintanance). For now, I'm just trying to find the reason for the script breaking down myself, so I will provide more information on that as soon as I get them.
Php is configured in the following way:
running on redhat 2.2.14-6.1.1 with apache 1.3.12
Thanks for any answer in advance,

I recompiled php with the changes from the patch, but could not see any remarkable changes. Could be, that the crashes occur slightly less often, but I'm not really sure as this is pretty hard to test. But I guess this is the right way to search - seems as if this was some header part? I rechecked the occurence of this crashes, and it seems to be in direct contact with sessions - pages without session do not crash at all (well, accept the xslt generated ones, but thats probably something different). I already tested to disable cookies, but this did not change anything :-(
Well, will try to learn how to debug and get some more information for you guys then...but may take some time;->

Can you please try with this snapshot:

It would also help if you could isolate the problem
to some short script..
