hi
Marcus ,
u must be correct ,
i have 32 G total memory ,
ive confiured in cache_mem =20000 M which is 20 G !!
ive noticed that squid hanged and got down after some hours of operating !!

i looked at all logs of squid and squidguard ,
i didnt find any errors from squid !

i looked at free memory by
#free -m
==>it was only 600 M free of memory
the # of process in squid was increasing gradually ,
as i remember it reached 890 process when squid go down !!

i rebooted the server and squid is working fine now !! i wish i found the
solution of the problem
now i decreased the cache_mem value to 10000 M instead of 20000 M
also i will try to increase the memory to 64 G as soon as possible .

any other suggestions ?

with my best regards
