Re: [squid-users] your cache is Running out of filedescriptors

It seems that you OS have support up to 12288 file
des.
but you have not started squid with more than 1024
file des.. so you will have to kill the squid process
and then you will restart it with command like that.

ulimit -HSn 2048 or more than that.

and than start squid
