#16325 [Opn->Fbk]: Memory leak causes DLLHOST to become large

ID: 16325 Updated by: iliaa@php.net Reported By: mail-php.net@kimihia.org.nz -Status: Open +Status: Feedback Bug Type: IIS related Operating System: Windows 2000 Server PHP Version: 4.1.2 New Comment: Please try using this CVS snapshot: http://snaps.php.net/php4-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-latest.zip Previous Comments: ------------------------------------------------------------------------ [2002-06-09 08:37:03] abo@irgendware.com I have the same problem using IIS5.1 with WinXP Pro with PHP4.2.1 as ISAPI module. During 2 seconds 300 MB of RAM where reservated for the service. I had to stop and restart all services and IIS admin to get the memory back. ------------------------------------------------------------------------ [2002-03-27 23:06:39] mail-php.net@kimihia.org.nz The setup: IIS5 has an ISAPI application mapping to php4isapi.dll Steps to reproduce: - Start IIS - Generate heavy load (~40+ hits / second) - Watch DLLHOST in the Task Manager. It takes more and more memory (40 - 45MB) - PHP error log begins reporting spurious errors (the page has no errors, but under heavy load it starts complaining about duplicate function definitions) Bug: #13324 - IIS stops serving PHP files but still serves static content DLLHOST disappears from the task list at this point. Other times it may begin taking 100% CPU and need to be terminated by hand. Killing DLLHOST usually causes it to be restarted and requests continue being served. Otherwise you may end up alternating between the two errors on bug #13324. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16325&edit=1
