U3, squid and swapping

[Jussi Silvennoinen <jussi_nahant silvennoinen net>]

After upgrading to U3 (x86), my little squid-box starting swapping without 
obvious cause. Things we're fine with 2.6.9-22.0.2.ELsmp.

After 4 days and 2.7 million requests, it's now at:

             total       used       free     shared    buffers     cached
Mem:          2025       1461        564          0          7         79
-/+ buffers/cache:       1374        651
Swap:         4094        885       3208

Squid is squid-2.5.STABLE12-4.i686 because of #167503, tried for sometime 
to convince RH support that the LARGEFILE-problem does exist in EL-package 
of squid to no avail, finally decided I have better things to do than to 
draw the problem in crayons to them.

Squid has no disk storage, only 'cache_mem 1300 MB'. Restarting squid 
releases the swap and things are okay again for a while. But swap starts 
to pick up slowly. Only squid, snmpd and postfix are running.

Anybody else seeing anything similar?
