#22815 [Opn]: Apache doesn't start

ID: 22815 Updated by: ianh@php.net Reported By: busia at tiscali dot it Status: Open Bug Type: Apache2 related Operating System: Linux Redhat 7.2 PHP Version: 4.3.2RC1 New Comment: I've seen this too with the worker MPM. but mine segfaults somewhere in a mutex_open/mutex_lock. I'll try enabling-zts on mine and see if that problem persists. The recommened solution is to use the PREFORK mpm, which doesn't use threading. If I get some time this weekend I'll try to reproduce it. BTW.. does this happen with 4.3.1?

I noticed one thing: apache doesn't create pid file, it doesn't arrive to create it. Using the old php4.4dev "200301041230" snapshot version all works well (it is the version that was installed before I tried to install php4.3.2RC1" outpuyt of gdb WITHOUT --enable-experimental-zts ------------------------------------ Starting program: /usr/sbin/httpd -X [New Thread 1024 (LWP 12706)] Program received signal SIGSEGV, Segmentation fault.

Try with starting httpd withing gdb: # gdb httpd (gdb) run -X ------------------------------------------------------------------------ [2003-03-21 16:34:48] busia at tiscali dot it I have tried --enable-experimental-zts without success. I'll try to test with the worker MPM but it's an "online" server and it should be not possible. I'll let you know. ------------------------------------------------------------------------ [2003-03-21 16:09:46] moriyoshi@php.net Using Apache2 SAPI module in worker model is highly discouraged because PHP has not completely been confirmed to be a thread-safe implementation. If you even want to use it within such a real threaded environment, you have to specify --enable-experimental-zts in the configure line. Then try configuring Apache2 to use prefork model and see if the problem still persists. ------------------------------------------------------------------------ [2003-03-21 15:58:57] busia at tiscali dot it I have also tried lastest 4.3.x stable snapshot from snaps.php.net. The problem persists ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
