We have an Apache 2.0.59 server on Windows 2003 running PHP 5.2.3. We are also running eaccelerator. Sometimes, PHP faults and brings down Apache with it. Considering this happens a few times a week, it's not the end of the world. The bad thing is that Apache "restarts", the logs show it spinning up new threads to serve pages, but it doesn't actually respond to any requests.On a similar, maybe related, note we have tried setting MaxRequestsPerChild on this system and when it is reached it exhibits simliar behavior. The logs say "Restarting apache. Starting X threads." etc. but it actually serves no pages.Anyone have any ideas?-Stephen
On the linux side, mod_php plus any sort of op-code caching (eaccelerator, APC, etc) all end up doing this after a little load. The only long term "fix" I know of is to run php using fastcgi. However, another solution is to have a script monitor the apache error logs for the segmentation faults, at which point it restarts apache completely. I do this now, and it works well. You can probably script a similar thing on windows.
