PHP 4.3.4 Windows Binary - No extensions enabled I have been fighting this battle on a number of servers and finally found the culprit. PHP4isapi.dll is constantly causing exceptions that eventually after awhile cause the HIGH ISOLATED memory websites in IIS 5 to become unstable where it eventually causes the dllhost.exe (high isolated memory for a website) to start crashing every 6-12 hours and produce the follow error in Event Viewer EVENT ID 37 Out of process application '/LM/W3SVC/6/Root' terminated unexpectedly. I ran a program called IISSTATE to watch the threads and found that with php4isapi enabled, everytime a PHP script executes, it produces 3 exceptions (1284.166c): Unknown exception - code 8001010e (first chance) (1284.10e4): Unknown exception - code 8001010e (first chance) (1284.10e4): Unknown exception - code 8001010e (first chance) If I reconfigure IIS to use php.exe, and unload the memory for the site so that it starts using the new php.exe setting immediately, then the Unknown Exception message stop being logged by IISState, when I change it back to use php4isapi.dll, I immediately start receiving these exceptions, 3 at a time for each time a php script is executed on the server. Anyone know why php4isapi.dll is doing this? Its the version that came with 4.3.4 windows binary zip release. I've reproduced this problem on 3 different webservers. This has been a problem even with earlier versions before 4.3.4 A search on google.com for php4isapi.dll problems results in tons of people having similiar issues with it like this one: http://groups.google.com/groups?q=php4isapi.dll+problems&hl=en&lr=&ie=UTF-8&oe=UTF-8&scoring=d&selm=bogd2u%2487f%241%40FreeBSD.csie.NCTU.edu.tw&rnum=3 -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
