Connection hangs...

[David Lee]

In problem-fixing, the "nicest" problems are those reproducible on demand.
Alas, this one is not nice.

System: Samba 2.0.6 on Solaris 2.7 (also see similar on Solaris 2.6).

Symptom (user perspective):  PC suddenly, spontaneously freezes and
eventually the connection times out. 

Symptom (log file): 
   [2000/02/15 09:27:30, 0] ../lib/util_sock.c:read_socket_data(474)
     read_socket_data: recv failure for 4. Error = Connection timed out

We have several hundred simultaneous connections from our NT-based
classrooms to about four Solaris servers.  All usually works very well. 
The above events are therefore relatively rare, but nevertheless still add
up to several occurences per day. 

Naturally, I'm not looking forward to debugging this one.  So just before
I start, is this a "known" problem?  Any fixes, workarounds?  Might it be
addressed in pre-2.0.7 (whose "WHATSNEW.txt" is not yet made)?  Any hints?
