Wincache crashing PHP

Hi,

We have been getting the following error in our web Servers (Windows 2008 R2 SP1 , IIS 7)

Faulting application php-cgi.exe, version 5.3.8.0, faulting module 4e537f4b, version php_wincache.dll, fault address 0x1.1.630.0.

Faulting application php-cgi.exe, version 5.3.8.0, faulting module 4e537f4b, version unknown, fault address 0x0.0.0.0.

Faulting application php-cgi.exe, version 5.3.8.0, faulting module 4e537f4b, version kernel32.dll, fault address 0x6.1.7601.17932.

It happens somewhat regularly and causes the server performance to degrade and then finally gets down

until we restart IIS as a temporal fix for this issue.

Any help will be appreciated.

Thanks,

Kristell
