zda sa, ze moj mail sa nejak nepaci antiviru, takze este jeden pokus:

squid mi v pravidelnych intervaloch (~minuty) vytazuje CPU takmer na 
100%, "cosi" (vid nizsie) urobi (~minuty) a tak dookola a zda sa ze to 
nesuvisi so zatazenim poziadavkami od clientov

na google zda sa, je to dost casty problem, ale riesenie sa mi 
nepodarilo najst, vie ho niekto ?

CPU AMD Athlon(tm) XP 1800+
MEM 1GB
kernel 2.4.27
squid 2.5.STABLE3-2.fc1

cache_dir ufs /var/spool/squid 2048 32 256 (na ext3 ja viem, ze to nie 
je optimalne, ale momentalne s tym nepohnem)
cache_mem 256 MB
