Previous Comments: ------------------------------------------------------------------------ [2006-05-09 16:45:24] zbowden at vt dot edu I'm seeing w3sp.exe processes crash but I'm not seeing the same Application Errors. The evidence I see are event id 1009's in my System Event logs saying the application pool terminated unexpectedly. Are you all seeing the application errors in the event logs or as pop ups? By chance are you seeing anything getting recorded in your event logs that correspond to this as well? ------------------------------------------------------------------------ [2006-05-08 21:25:02] paul at routingcore dot com I get the same thing. I hadn't updated since 5.0.4, which works fine for me. As soon as I drop 5.1.4 in I get the application errors for w3wp.exe. I set IIS to recycle the worker threads every couple of minutes to see if the frequency of the errors would increase, and they did. ------------------------------------------------------------------------ [2006-05-08 15:48:22] gravityworksllc at hotmail dot com I can validate this error. I get this along with the pool process crashing. This was fine in version 5.12. If you need more information on the errors please let me know.

This did not happen with 5.1.2 or earlier versions. Running IIS 6.0 on Windows 2003 Server Enterprise. Running PHP in ISAPI mode. w3wp.exe processes crash throughout the day, about 20-30 times. Several process instances will usually crash together at the same time, and then be ok for a couple of hours until happening again. Error is: w3wp.exe - Application Error : The instruction at "0x01b55c80" referenced memory at "0x01b55c80". The memory could not be "read". The memory address is always either "0x01b55c80" or "0x01b55c90". Here is a link to my PHPinfo(): http://mail.fast4gl.net/phpinfo.php Reproduce code: --------------- Running vBulletin (3.5.4). Can't track down any code which produces the crash. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37366&edit=1
