I've been noticing that in the error_log file (/etc/httpd/logs/error_log) Apache crashes every 2 or 3 minutes similar with the following error messages.
[Tue Feb 26 13:19:35 2008] [notice] child pid 26473 exit signal Segmentation fault (11)

I suspect the problem to be related to PHP but I do not know how to track which PHP script or function is causing this.
i have upgraded to the latest PHP (4.4.8) and Apache (1.3.41) in the 4.x and 1.3.x series but to no avail. Any suggestions are appreciated.
FYI, here is the configuration
