networking bug?

[Dave Marquardt]

I've got a problem.  We have a VAX-11/785 running 4.2BSD, and every two weeks 
or so, telnet and rlogin stop working.  This is a BIG problem, because many of 
our users log in via Bridge terminal servers.  The Bridge box is also no
longer able to talk to the VAX, and disconnects all sessions to that
machine.

In checking out the problem, I tried using telnet from the VAX to another
machine, and got this message:

	Out of buffer space.

This message occurs even after the Bridge box disconnects most of the 
sessions in progress because it can't talk to the VAX any more.
This makes me suspect that some networking code is not freeing up memory 
correctly (or perhaps not at all).  Has anyone else seen this and come up with 
a fix or work-around?  Any help would be appreciated.  Please send mail to
me.

Also, if it helps any, we're using Excelan's EXOS 204 Ethernet controller
and the driver provided by Excelan.  If you need any further information,
send me mail.  Also, if there is interest, I'll post a summary later.

	Thanks in advance,

		Dave Marquardt
