looking at php-cgi.exe memory dumps,i see

I am not sure what is causing the php-cgi.exe process to get hung right after loading odbc dll. I am seeing all the php-cgi.exe process getting hung with the same behavior.Killing all the php-cgi process will get back everything up.

This is a bug in the wincache module. A fix is in the developer channel.

https://bugs.php.net/bug.php?id=68107

From the bug:

Please pick up 1.3.6.2, which has a fix for this issue.

Additionally, 1.3.6.2 adds a new setting that can be used to disable Shared Reader/Writer (SRW) locks. By default, WinCache uses SRW locks. Disabling them will incur a slight performance hit, but is robust against byzantine failures where php-cgi.exe instances get killed while WinCache is holding a shared lock. The new php.ini setting is:

wincache.srwlocks=0 ; default is 1.

1.3.6.2 is available out on SourceForge in the developer releases folder.

http://sourceforge.net/projects/wincache/files/development/
