Description:
------------
We have been successfully using PHP 5.1.2 for several months in our server environment.

Only upgrading PHP to 5.1.6, with no other software upgrades, has resulted in frequent w3svc crashes and subsequent application pool terminations.

The system log includes such errors as:

---
A process serving application pool 'Site1' terminated unexpectedly. The process id was '5796'. The process exit code was '0xc0000005'.

A process serving application pool 'Site2' terminated unexpectedly. The process id was '5212'. The process exit code was '0xffffffff'.

A process serving application pool 'DefaultAppPool' terminated unexpectedly. The process id was '5824'. The process exit code was '0xc0000005'.
---

We have run the IIS Diagnostics Debug Diagnostics Tool on these crashes, which has resulted in the following report for each crash:

I'm getting precisely the same debug output from IIS Diagnostics Debug Diagnostics Tool running on a Windows Server 2003 SP1 with the build php5.2-win32-200609131430.zip

If you want I can provide you crash dumps.

Same error here:

A process serving application pool 'mysite1' terminated unexpectedly. The process id was '2828'. The process exit code was '0xc0000005'.

A process serving application pool 'mysite2' terminated unexpectedly. The process id was '3132'. The process exit code was '0xc0000005'.

etc.

The error occurs
- each time, the w3svc is recycled because of idle-timeout (default 20 min.)or uptime 1740 min.
- sinze version 5.1.4 of php

If idle-timeout occurs, no script is running at this moment!
Only the isapi is loaded.

Same error, also if no php.ini exist, means no extensions are loaded

Im getting this exact error also... i have disabled the application pool recycle functions in the IIS server it stil happens this emm problem but it takes a couple of days before it does simple idiot fix is to just goto the server and do a load on a php page for the application pool and then it works again for a couple of days. If i reactivate the recycle functions ill end up with counltess of php page downtime sessions where i have to go and reload a php page localy on the server to fix it.. i run 5.1.6 as php rel ver my question is... Is there a older versions of the php releases that do not cause this effect? untill there is a permanent fix for it.

Is this the same as bug report 37483?

Does anyone know if this was ever solved or what the best workaround is?  I have a server that is showing this problem and need to fix it asap.

Thanks in advance.

Most easiest way to reproduce:

access and loginto phpMyAdmin 2.10.2, select database, and attempt to browse a table (not structure, actual table)

Also re-produceable via attempting to browse a sql table through the mysql GUI application.

Had the same problem on Win2003SP1, tried this with the iisreset which seems to do the trick: http://support.microsoft.com/kb/842493
