[squid-users] is there any thing wrong from cache manager logs ?!!

hi all ,
ive tested squid 3.3.9 with smp , abut after some time i haad workers 100 %
cpu !!!
dont know why , just loaded some users

i tried with mem pools off
reduced cache mem
made cpu mapping

but no solution ,

in the end i removed the acl web filtering and monitored squid , it didnt
hang agian , but i have some slow on squid !!!
---------------------------------

but i also want to investigate if there is any annoying other thing
here is logs from cache manager :
