Hello,

I have i386/PAE system (php, apache22, mysql) running on 7-STABLE and I 
can see strange behavior after upgrade from 7.0: Apache does not free 
memory, for example:

CPU: 31.2% user, 0.0% nice, 12.8% system, 0.7% interrupt, 55.3% idle
Mem: 3520M Active, 3705M Inact, 465M Wired, 314M Cache, 112M Buf, 12M Free
Swap: 4096M Total, 105M Used, 3991M Free, 2% Inuse

then apachectl graceful

CPU: 28.3% user, 0.0% nice, 8.6% system, 0.0% interrupt, 63.1% idle
Mem: 631M Active, 3126M Inact, 353M Wired, 213M Cache, 112M Buf, 3693M Free
Swap: 4096M Total, 1844K Used, 4094M Free

Some graph: http://max.af.czu.cz/memoryload.png

I know before upgrade was memory using about 2,5GB, now much more, 
apache sometimes crash.

Thanks for some help
