ID: 7452 Updated by: sniper Reported By: yfaktoro@nusphere.com Old-Status: Feedback Status: Closed Bug Type: Apache related Assigned To: Comments: Please try latest CVS snapshot from http://snaps.php.net/ and if this problem still exists when using it, reopen this bug report. --Jani Previous Comments: --------------------------------------------------------------------------- [2000-12-04 09:19:15] sniper@php.net Could you please check if this happens also with PHP 4.0.4RC3: http://www.php.net/distributions/php-4.0.4RC3.tar.gz --------------------------------------------------------------------------- [2000-10-25 11:59:51] yfaktoro@nusphere.com compile mod_php with-mm on RedHat 7 with oonly 34M of shared memory. Also compile apache to use mod_php (enable_module=most) ps_mm_initialize calls mm_create() and passes 0 for pool size. That causes mm_create to try to get hardcoded 67M of shared memory. mm_create fails b'zeachine only has 34M ofshared memory available. As a result, data->mm is NULL and data->hash will also be assigned to NULL returned from mm_caloc, which will later cause a crash in ps_mm_destroy. This means that apache crashes on startI think ps_mm_initialize should check the return from mm_create and pass something other than 0 to it. --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=7452
