I have a question about the loopback interface found on our Sun
workstations.  Our problem is that when we do a netstat -a, a bunch of the
following connections are formed (ie. dozens):

Active connections (including servers)
Proto Recv-Q Send-Q  Local Address      Foreign Address    (state)
tcp        0      0  loopback.2703      loopback.sunrpc    TIME_WAIT
tcp        0      0  loopback.2702      loopback.sunrpc    TIME_WAIT
tcp        0      0  loopback.2701      loopback.sunrpc    TIME_WAIT
.
.
.

These go away after awhile, but we can't figure out why they should be
there in the first place.  Here is our entry for loopback:

127.0.0.1   loopback lb localhost loghost datehost

Here's some more funny stuff.  One another Sun we have an entry of:

127.0.0.1   loghost me loopback localhost

and there's no loopback connections created during a netstat -a!  What
could be the difference?

We are running Sun OS 3.3 on our 'problem' Sun, and 3.4 on our 'good' Sun.

Thanks in advance.
