ID: 44422 Comment by: d dot runkel at nanotron dot com Reported By: drew at tribalectic dot com Status: Open Bug Type: IIS related Operating System: Windows 2003 Server PHP Version: 5.2.5 New Comment:
We have the same here using Server 2008 (IIS7) / PHP 5.2.6. I lowered the Idle-Timeout of the default App Pool from 20min to 1 min. Whenever i browse a Page containing phpinfo as a single line and wait for the timeout events 5186 ( Apppool idle shutdown) 5009 (Appool crash due to php5isapi dll heap problem) are logged. I just tested with actual snapshot 5.2.7 and the problem persists. Any updates on this ? Previous Comments: ------------------------------------------------------------------------ [2008-03-17 20:00:33] drew at tribalectic dot com I have upgraded to 5.2.6RC3-dev and the problems continue. This is killing our server with these resets, we really need HELP and the server is live with lots of traffic so the sooner the better!

Can I just use that to upgrade or do I need to manually overwrite all files? Is the problem I have described fixed in the latest version? This is a production site so I am a little worried about tinkering too much. -Drew ------------------------------------------------------------------------ [2008-03-12 21:44:42] [EMAIL PROTECTED] 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 ------------------------------------------------------------------------ [2008-03-12 18:35:33] drew at tribalectic dot com Description: ------------ PHP 5.2.3 was causing server crashes every so often on the application pool.
