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
 2424 squid 15 0 1122M 864M 1440 S 3.9 42.6 1999m 0 squid
