mod_mem_cache Issues

["Email Lists" <lists@xxxxxxxxxxxxxxx>]

I've been trying to setup apache to do memory caching of my static files, I run 4 servers serving only .js and .css files as well as some images. this machines have 2 gigs of ram and only run apache. I've been able to use the file cache without a problem and can see it caches them in the error log with level debug but when i enable it for memory it will always re request the file even though it says it cached the url

Here is some info

[root@static1 ~]# cat /etc/httpd/conf.d/cache.conf

Disk cache works perfectly for when i want to cache output of dynamic pages but for static files it would be great if i could just spit them out from memory. I have tried making the size of the cache bigger in memory to 1 gig still same issue.
