Hello List,
My squid server runs on a PC with a P4 1.8Ghz machine with 512MB of
SDRAM and has a separate 40GB IDE 7200 rpm Hard drive of which only 20GB
for cache, and an additional 2GB on the main hard drive. It runs RH
Linux 9. I observed that it just stopped responding to requests, and
upon inspection of the cache logs this is what I found

I then cleared out the cache and rebuilt it all over and the problem
cleared up. Pls could anyone tell me what could have caused this, as I
would like to avoid such occurrences in the future. I know it has
something to do with the cache store, but what exactly is it?
