This offset is in WinCache's memory allocation function for managing shared memory segments. This crash indicates memory corruption in the shared memory segment. The only recovery for this kind of corruption is to restart the site. That's the only way to be sure that all of the php-cgi.exe process instances are closed, and the shared memory segments are released.
Investigating this is difficult, since it requires getting a full heap crash dump from all of the php-cgi.exe instances at the time of the first crash, and then groveling through the shared memory segments to figure out who could have possibly scribbled on the shared memory segment.
Please send me your wincache config settings in a private message. I'd like to see if you have the wincache.srwlocks option still enabled. My first suggestion would be to turn that off (wincache.srwlocks=0).
Thx!
