Prefork has had no segfaults in more than two days, versus 10 hours for the first segfault with the worker mpm (then a mass of segfaults a day or two later). Previous Comments: ------------------------------------------------------------------------ [2009-05-07 22:42:58] jani@php.net Can you just try with prefork MPM so we can make the list of possible issues a bit shorter..? And yes, supposedly PHP is thread safe, just some libraries might not be and of course there might be bugs in PHP. ------------------------------------------------------------------------ [2009-05-07 19:08:55] jimbobpalmer at gmail dot com Is php not thread safe? ------------------------------------------------------------------------ [2009-05-07 14:00:49] jani@php.net That explains it. You propably wouldn't have any problems if you didn't use threaded MPM. Try the more stable prefork MPM instead. ------------------------------------------------------------------------ [2009-05-07 13:44:47] jimbobpalmer at gmail dot com Worker MPM + apache2handler ------------------------------------------------------------------------ [2009-05-07 13:19:30] jani@php.net Exactly what MPM are you using and what PHP SAPI module? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
