Squid stops working after like a day and i need to restart it to let
user browse or use internet. Any parameters to look for? Out of 2 GB RAM
only 200 MB RAM is left free when i find squid halted (before restrting it).

take long before it will reach this limit! what happens then? does it
start discarding old cache objects or what?
