Lately I have been receiving a lot of segmentation fault warnings on my web-server.

The warnings look like:

[notice] child pid xxxx exit signal Segmentation fault (11)

I have consulted with the server provider (it is a dedicated redhat enterprise server) and they could not find anything.

What I have done so far:

Since the error I have already tried the following:

• I have added more ram
• I have turned off / turned on several php modules (they sent me to a web-page someone had the same problem, caused by an excessive amount of php modules)

At the moments the warnings occur, there seems to be plenty of free ram left and the number of processes is very low (the number of httpd processes is about a quarter of the maximum allowed).

What can be causing these errors?

Edit: current versions

• apache: 2.0.52
• php: 5.2.8
• RHEL 4

Edit 2: Although I asked this a long time ago, I never was able to solve it until I upgraded to php 5.3.
