Hi,

I have a windows 2003 server with iis6 production server, which runs mu companies website (wordpress), and I have a issue with that fast-cgi hangs a lot and connections to the server times out. The server perfomrce very slowly also. I check the server's eventview today and there is a lot of error reports on:

Faulting application php-cgi.exe, version 5.3.19.0, faulting module kernel32.dll, version 5.2.3790.5069, fault address 0x00021671.

EventID 1001 appliction error: Fault bucket -772687241.

I have a ton of these in the log..

Any ide helping me in the right direction to solve this issue is very appreciated!

Thanks!
