Description:
------------
As per customer:

Faulting application php-cgi.exe, version 5.3.2.0, time stamp 0x4b8ecac5, faulting module php_wincache.dll, version 1.1.427.0, time stamp 0x4bd620f4, exception code 0xc0000005, fault offset 0x00009a30, process id 0x1680, application start time 0x01caf02faeb1fcb9.

Whenever this happens I have to manually restart the IIS web service (the app pool would probably be sufficient) before any requests will be handled.

This means somehow we are corrupting the shared memory or locking is not correct.

I understand this happens when a process PID recycles and then the new process tries to free memory which was allocated by the old process. I have checked in a fix for this.
