Dear all, I am sure this question would have been posted many times. I read a few threads, but my requirement or setup is a bit different. I am running Squid2.6stable18 on Ubuntu Server 8.04 Server 64-bit installed on Sun Fire X4150 Server with 8GB RAM + 8 SAS HDD's - RAID 5 + 2 Quad Core Intel Xeon Processors. I have both LTSP and WinXP clients using Squid. Many times i have noticed, squid stops responding, the browser keeps trying to connect and i don't see any error in cache.log or store.log. My only way out is to restart squid.
Usually means Squid is doing something with its on-disk storage.
I read through cache_mem, my current configuration is 100MB, i changed it to 128MB, but squid couldn't start saying the cache_mem is more than cache_disk size. Why does this happen and what is the recommended configuration for the hardware i have?
You are missing a cache_dir option. Which means Squid-2 will be using the default and very inefficient 100 MB ufs formatted storage.
Squid-3.1 and later are the only releases of Squid where cache_dir can be fully removed from the config.
Either define a cache_dir to use the disks or setup the "null" cache_dir type for memory-only storage.
squid.conf: Please donot compare this config to my other posts, as this is on a different server and it has a very basic configuration. visible_hostname sunserver hierarchy_stoplist cgi-bin ? acl QUERY urlpath_regex cgi-bin \? no_cache deny QUERY
Drop 'no_cache' use instead: cache deny QUERY
