#26861 [NEW]: IIS ISAPI Lockup

From: ryan at rbftpnetworks dot com Operating system: Windows 2000 Server PHP version: 4.3.4 PHP Bug Type: IIS related Bug description: IIS ISAPI Lockup Description: ------------ For the time that I am on a Windows server, before I changeover to the wonderful Linux, I have been running the ISAPI module of PHP under IIS, because the sites being run are high traffic, production sites that require speed. Every now and again, approx 1hr-36hrs, the machine will explode to FULL CPU and I would get the error message below in the Server Logs. The CPU power would be taken up by the dll that runs the IIS PHP Isapi in protected web mode. I would either have to restart IIS (if I can gain terminal access) or restart the server. Upon searching the internet for other people with the same problem, I found many people - that still have not found a resolution to this problem. I feel that my case is slightly different. ERROR MESSAGE: The HTTP server encountered an unhandled exception while processing the ISAPI Application ' php4ts!php_execute_script + 0x21F + 0x8B9B1B41 '. For additional information specific to this message please visit the Microsoft Online Support site located at: http://www.microsoft.com/contentredirect.asp. Reproduce code: --------------- The websites are using the well known PHP-Nuke scripts with MySQL Winnt on the same server. Expected result: ---------------- The server to run stable. Actual result: -------------- The Server page generation times would increase, the server cpu will go up to 100% usage. -- Edit bug report at http://bugs.php.net/?id=26861&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=26861&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=26861&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=26861&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=26861&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=26861&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=26861&r=needscript Try newer version: http://bugs.php.net/fix.php?id=26861&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=26861&r=support Expected behavior: http://bugs.php.net/fix.php?id=26861&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=26861&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=26861&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=26861&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=26861&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=26861&r=dst IIS Stability: http://bugs.php.net/fix.php?id=26861&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=26861&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=26861&r=float
