FD problem

Hi all,

While investigating why I was running out of FDs I discovered that one of
our sites (the network 193.190.145.0) was consuming most of them. In the
cachemgr they show up like this:

 154 Socket 61 0 193.190.145.59.1633 193.190.145.0
 155 Socket 49 0 193.190.145.54.2449 193.190.145.0
 156 Socket 107 0 193.190.145.226.1861 193.190.145.0
 157 Socket 117 0 193.190.145.56.3175 193.190.145.0
 158 Socket 69 0 193.190.145.226.1763 193.190.145.0
 159 Socket 66 0 193.190.145.52.1166 193.190.145.0
 160 Socket 27 0 193.190.145.58.1963 193.190.145.0
 161 Socket 77 0 193.190.145.48.1285 193.190.145.0
 162 Socket 15 0 193.190.145.63.1789 193.190.145.0
 163 Socket 111 0 193.190.145.55.1712 193.190.145.0
 164 Socket 102 0 193.190.3.1.3193 http://morello.wildnet.co.uk/
 ...
 ...

I'm used to seeing entries like FD 164 but what's with the other ones?

netstat gives:

dalet.belnet.be.8000 193.190.145.226.1437 8760 0 17520 0

... (there are several hundreds of them)

It seems like they open a TCP connection but never use it. The connections
appear to stay established until TCP eventually times out.

The site uses Netscape 3 on NT to access our proxy (squid-1.1.15 on
Solaris).

Anyone seen something similar?
