I have squids running on both OSF v3.2g and v4.0b, and default kernel
setting for filedescriptors is set at 4096..

98/02/17 14:53:08| Starting Squid Cache version 1.1.18 for
alpha-dec-osf3.2...
98/02/17 14:53:08| With 4096 file descriptors available

98/02/17 15:06:15| Starting Squid Cache version 1.1.18 for
alpha-dec-osf4.0...
98/02/17 15:06:15| With 4096 file descriptors available

But then of course my usage doesn't even touch 500, therefore I can't
comment when filedescriptor usage rises above 1000...

That would be my gut feeling, but I don't think the gut feeling of one
person is
enough to make this sort of decision on. It's quite possible that
there are setups
using digital unix that _don't_ experience this problem at all. If so,
I'm sure
they'll put their hands up.

Personally, when there's performance issues like this, I prefer to
_test_ a setup,
before I commit.

Did you read the documentation AND the FAQ?
If not, I'll probably still answer your question, but my patience 
will
be limited, and you take the risk of sarcasm and ridicule.
