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?

The parent process remains active but it seems to wait something that
doesn't happen. it seems apache cannot complete startup process and
wait, wait, wait.
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"

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.

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.

I have also tried lastest 4.3.x stable snapshot from snaps.php.net. The
problem persists
