Memcache fast-cgi php apache 2.2 windows 7 creating problems

I am trying to run memcache, fast-cgi with apache 2.2 + php on a windows 7 machine. If I don't use memcache everything works fine.

The moment I disable extension=php_memcache.dll in php.ini everything returns to normal.

Once I start apache, the apache logs say:

[Wed Jan 12 18:19:23 2011] [notice] Apache/2.2.17 (Win32) mod_fcgid/2.3.6 configured -- resuming normal operations
[Wed Jan 12 18:19:23 2011] [notice] Server built: Oct 18 2010 01:58:12
[Wed Jan 12 18:19:23 2011] [notice] Parent: Created child process 412

[Wed Jan 12 18:19:23 2011] [notice] Child 412: Starting thread to listen on port 80.

and after accessing the page (the page just has echo phpinfo()) I get this error in the error.log:

[Wed Jan 12 18:20:54 2011] [warn] [client 127.0.0.1] (OS 109)The pipe has been ended.  : mod_fcgid: get overlap result error
[Wed Jan 12 18:20:54 2011] [error] [client 127.0.0.1] Premature end of script headers: index.php

I have php_memcache.dll in my ext directory and httpd.conf is like this:

LoadModule fcgid_module modules/mod_fcgid.so

FcgidInitialEnv PHPRC "c:/php"
FcgidInitialEnv PATH "c:/php;C:/WINDOWS/system32;C:/WINDOWS;C:/WINDOWS/System32/Wbem;"
FcgidInitialEnv SystemRoot "C:/Windows"
FcgidInitialEnv SystemDrive "C:"
FcgidInitialEnv TEMP "C:/WINDOWS/Temp"
FcgidInitialEnv TMP "C:/WINDOWS/Temp"
FcgidInitialEnv windir "C:/WINDOWS"
FcgidIOTimeout 64
FcgidConnectTimeout 32
FcgidMaxRequestsPerProcess 500

<Files ~ "\.php$>"
  AddHandler fcgid-script .php
  FcgidWrapper "c:/php/php-cgi.exe" .php
</Files>

So the problem has to be related to memcache because if I disable it, fast-cgi seems to be working fine. Are there any possible reasons for this??

The memcache service is running… I can check it through control panel->services.
