PHP may be kind of an unknown under threaded servers. While it is  
commonly stated that the PHP core should not have any problems with  
threading, you may have compiled in libraries that are not  
threadsafe, and can give you strange and untractable problems under  
load.

Perhaps you might do better with the prefork MPM?
