Re: [squid-users] memory leaks

Hello All,

News from my squid box.

I have changed fs from reiserfs to ext2 if you remember (due to the
suspect that it eats RAM).
And after cache dir is filled up ~95% I still get 300 MB of RAM gone
again....

It is a real mystery for me where the hell all RAM has gone, but I suspect
squid. Because when squid was turned off I had ~ 350 RAM in the buffers
and cache ... and now I have only:

             total used free shared buffers cached
Mem: 516312 510936 5376 0 17984 95408
-/+ buffers/cache: 397544 118768
Swap: 248968 0 248968

Any ideas ?

Regards,
Edvard Chitro
