Page timeout after enabling APC

I installed APC on our Windows dev server. After turning on APC and restarting apache, our pages do not load. They time out and I just got a reset connection in the browser. Other scripts on the server, such as phpmyadmin, also do not load.

Here is our system configuration:

Windows 2003 Server
Apache 2.2.22
PHP Version 5.3.15
APC Version 3.1.11

Check on apc.phpI see hits of 80% and misses 20%.

APC Runtime Settings

apc.write_lock    1

I saw files created in the designated temporary folder with names such as .apc.a00532, but they havefile size 0

I also checked the php error log and see nothing there.

Any help is greatly appreciated, thanks in advance.
