After a couple of hours Squid took all mem available.
It didn't.
It's just a matter of how to read the amount of free memory in Linux.
It's not easy as the OS uses any free memory as buffer/cache for the
filesystem.
Under normal operation there should be around 5-12MB "free" memory, if
not there is something wrong..
What is causing this ? I had the same problem when using 2.5.
Mem: 906752k total, 902464k used, 4288k free, 32168k buffers
Swap: 3911816k total, 4k used, 3911812k free, 637096k cached
You have 657 MB free. Plenty free memory there.
"free -t"
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
2781 proxy 15 0 174m 168m 2616 S 1.0 19.0 1:31.55 squid
And Squid is using 168 MB.
So everything is just in order. It's just that Linux does not have a
simple "free memory" value. The best approximation is the "Free +/-
buffers/cache".

Hi,
Henrik what do you think from these memory values?
[root@proxy root]# free -t
total used free shared buffers cached
Mem: 2075036 2068700 6336 0 475280 595452
-/+ buffers/cache: 997968 1077068
Swap: 4194256 248 4194008
Total: 6269292 2068948 4200344
PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU COMMAND
