Basically you are right, I think this would be an option for Toens Bueker,
but I am running a small company internet server and I would be really
surprised if I would have more than 150 used fd's (all fd's not just
Squid's). And I definitely saw this behaviour never before 1.1.9. The
sockets get closed, but it usually takes a while for that to happen (CLOSE
state means that the client closed the socket, but Squid hasn't yet). And
currently it only happens with a certain client, that's why I suspected
that it only happens with certain browsers. Tomorrow I will check what
browser that client uses.
