Previous Comments: ------------------------------------------------------------------------ [2008-03-04 02:12:23] crrodriguez at suse dot de Please report SUSE package problems at http://bugzilla.novell.com/ NOT here, unless you are sure that this problem is still present in php.net sources. in both cases, you must provide a test case in order to reproduce the problem and fix it. Thanks for your attention, ------------------------------------------------------------------------ [2008-03-03 15:08:39] dmitry dot dulepov at gmail dot com It is hard (if not impossible) to use CVS snapshot on a production server. May be someone from development team can check what happens in source code? Or is there anything that makes you think the problem is solved in CVS? ------------------------------------------------------------------------ [2008-03-03 12:52:35] jani@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows (zip): http://snaps.php.net/win32/php5.2-win32-latest.zip For Windows (installer): http://snaps.php.net/win32/php5.2-win32-installer-latest.msi ------------------------------------------------------------------------ [2008-03-02 09:51:19] dmitry dot dulepov at gmail dot com Description: ------------ From time to time Apache crashes inside PHP. It is impossible to reproduce by executing a single script but this happens several times a week. I cannot get a backtrace because this is no single script that crashes. It just crashes from time to time. I use official distributions from SuSE 10.3.
