winsock error 10048 (errno 112) from ssh

[Mark Paulus <mark dot paulus at mci dot com>]

I am running 
CYGWIN_NT-5.0 WS117V0509 1.3.22(0.78/3/2) 2003-03-18 09:20 i686 unknown unknown
Cygwin
under Windows 2000 w/latest service pack.  I have noticed this little odd
behaviour for a while, and I have tried a couple of upgrades to ssh to see if that
will alleviate the problem, but to no avail.

When running ssh, I notice that after a variable amount of time, my ssh session
locks up.  I have also noticed this using scp with large transfers.  The amount
of time between locks can vary, but lately it seems to be happening more
frequently.

I have run an strace on the session, and I can include it if needed, but it's 4+ MB,
so I won't unless asked for. 

However, here is the part that is wierd:

  101 188230376 [ttyin] ssh 3220 fhandler_pty_master::accept_input: about to write 1 chars to slave

up there at the line headed 91, there is the winsock error 10048, which I don't understand.
The pattern of the file shows that the next file should be either 
fhandler_termios::line_edit: char0x1B
or
select_stuff::wait: woke up.

But I don't get either.  just a hard lock up.

Has anyone else seen this, or have any ideas as to why this might be happening??

Thanks.
