Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.2-win32-latest.zip .. And try the snapshot. Previous Comments: ------------------------------------------------------------------------ [2007-02-13 18:18:48] [EMAIL PROTECTED] You can start with disabling eaccelerator and any other zend extensions you may have loaded. ------------------------------------------------------------------------ [2007-02-13 18:07:17] stojmir at on dot net dot mk I really have no idea on how to narrow down the code that could reproduce the crash. It could be anything from the thousands of lines of code in Drupal. Any hints? What else can i do in order to help you guys identify and resolve this? ------------------------------------------------------------------------ [2007-02-13 17:33:37] [EMAIL PROTECTED] Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2007-02-13 16:49:39] stojmir at on dot net dot mk Description: ------------ My apache crashes on random intervals (usually 10 hours): zend_mm_heap corrupted zend_mm_heap corrupted zend_mm_heap corrupted [Tue Feb 13 17:28:01 2007] [notice] child pid 14881 exit signal Segmentation fault (11), possible coredump in /var/apache-dump Im guessing its related with the zend memory menager, but who nows, im not really into it so i cant be sure. PHP version 5.2.1, Apache 2.0.55, RedHat Enterprise Linux with 2.6.9-42.0.8.ELsmp on a x86_64 machine with dual core Xeon. The site is hosting a Drupal installation with about 3000 users at a time.
