How many users is your Squid box serving? It's strange that there is no
errors. Where have you defined the cache_log directive in your squid.conf?
+- 300~400 users simultaneously
cache_access_log none
drop cache_access_log ts a deprecated option.
2.6+ use plain new access_log now.
Also, why no logging of where users are visiting?
Amos
cache_log /var/log/squid/cache.log
cache_store_log none
cache_dir aufs /var/spool/squid 110000 72 256
cache_mem 256 MB
When you say "after some time running .. squid proccess refusing
connections", is it a few minutes or hours or even days?
an accurate time does not exist, after some hours, when the load increases ..
Can you post the output of "squidclient mgr:info"?
Posting your squid.conf may help too.

somebody knowns wat=B4s happens ?!
Is that the output of "squid -v"? By the way, what is the 3D reference
in your compilation parameters for?
Did you install Squid from FreeBSD ports or did you compile it yourself?
thanks..
