Hi All I am using squid 3.1.10 on CentOS 6.4 64 bit OS. I have configered squid.conf for "cache_dir" to cache_dir "/opt/var/spool/squid " . by giving "cache_dir ufs /opt/var/spool/squid 100 16 256" As per the documentantion it means I am allowcating 100 MB of cache space. And I have /opt/ partiion free size of 600 GB But when I restart the service I get warining message WARNING cache_mem is larger than total disk cache space! I should not be getting this message, because my cache space (ie /opt/var/spool/squid) has about 600 GB of free space. I have searched the archive and did a google search, all most all the resource say I need to increas the cache space. Here I have 600 GB free space I need guidance on why such message is coming when I restart the service thanks Joseph John
