[squid-users] Any way to stop squid from using too much memory

Hi Henrick!

Is there any way that I can stop squid from using to much memory?

I have redhat 7.0 kernel 2.2.17, squid 2.4 Stable (lastest snapshot), 192MB, 2 9Gb UW SCSI HD (partition into 4MB partitions).

I am also using the GNU Malloc lib.

Right now my squid is at also most 100MB.

My system swap is almost : 20MB
