There is an unexplained behavior that we've seen on a few machines we have
with emacs. These are Redhat Enterprise Linux boxes that we usually ssh to.
Xforwarding works fine. All X apps including emacs work fine. Then, after
a long time (weeks or months), emacs stops appearing in its own window when
you ssh into the box. Instead, after a long wait, it croaks with something
like "Connection Lost to Xserver. localhost 10:0."
At this point, you can open ALL X applications except for emacs. Xeyes,
xclock, xterm, firefox all work! But not emacs. "emacs -nw" does work, and
emacs in its own Xwindow works if you're directly on the machine. However,
emacs will not open without the -nw option thru ssh. (Even though it did
while the machine was running for quite some time.) Restarting the machine
fixes the problem.
Has anyone ever seen this behavior? The emacs version is 21.3.1.
Any help would be greatly appreciated.

Can you do "netstat -a" (look for listening ports in the 6000-6100 range)
when the problem occurs ?
Also, do "echo $DISPLAY".
Try to run "naked" emacs - emacs -q , what happens ?

Weirdly enough, this behavior went away when I tried it this morning (after
a couple of days). Emacs is working again. I can't explain it at all.

OpenSSH 3.8 changed the way X forwarding works, with the result that
many programs break in confusing or subtle ways.
If that's what you're using, you can get the old behaviour back by
doing "ssh -Y hostname", or setting "ForwardX11Trusted yes" (in
addition to "ForwardX11 yes") in your ~/.ssh/config.
