Ethernet loopback interface problem

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: loopback lb localhost loghost datehost

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