If this is normal then I am quite worried. Our squid is not really a busy
one, I would imagine that in busy sites, their NOVM squid will use up a lot
more fds under heavy load. Stock Linux only comes with 256 fds, which will
run out very quickly. Can other NOVM users check your squid's fd usage too?
 I'm wondering if this is related to the problems reported by other NOVM
squid users.
