ID: 17414 Comment by: ethan-php@etuttle.com Reported By: thom@planetarytramp.net Status: Open Bug Type: Apache2 related Operating System: Linux PHP Version: 4.3.0 Assigned To: aaron New Comment: I am also experiencing this bug. It is annoying because it causes apache to silently die every night when the logrotate script runs (installed from the "apache2-common 2.0.43-1" debian package) install details: Apache/2.0.43 (Debian GNU/Linux) PHP/4.3.0RC4 php configure: ./configure --with-mysql=/usr --with-imap --with-imap-ssl --with-apxs2=/usr/bin/apxs2 --with-gettext --with-xml running mpm-prefork error log: [Fri Jan 10 11:59:41 2003] [notice] seg fault or similar nasty error detected in the parent proces "apache2ctl restart" doesn't crash when php module isn't loaded If I can help, let me know!

Did you personally see it crash with prefork? I did not and I am running Apache 2.0.43 (prefork) with PHP 4.3.0-dev and surprisingly it served some 10,000 requests to PHP script doing GD image manipulations without a single crash. ------------------------------------------------------------------------ [2002-12-08 17:40:58] thom@planetarytramp.net How else do you explain the fact that all current versions of apache2 segfault reproducibly with no options to php barring --enable-debug and --with-apxs2? And the *exact* same install functions *perfectly* when php is not loaded. I've been told this is producible with prefork, too. *Please* reread the back traces i've put on this bug. I'm happy to help in anyway, just don't close valid bugs as bogus. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
