Summary: idle freezes when run over ssh

Initial Comment:
Python 2.3.4 (#2, Aug 13 2004, 00:36:58) 
[GCC 3.3.4 (Debian 1:3.3.4-5ubuntu2)] on linux2
IDLE 1.0.3      

When running idle over an ssh link, idle freezes after
an unpredictable length of time. Over 3 days the
longest it has stayed allive for is ~4hrs, but a few
minutes before freezing is the norm. Niether idle nor
python are consuming cpu time once frozen. I can find
no definete recipie to bring about the freeze, although
(I think) there has always been at least one editor
window open when it happens. There is no output on
stderr, or other diagnostics that I can see.

ssh server(ubuntu warty):
OpenSSH_3.8.1p1 Debian 1:3.8.1p1-11ubuntu3.1, OpenSSL
0.9.7d 17 Mar 2004

ssh client (RH9):
OpenSSH_3.5p1, SSH protocols 1.5/2.0, OpenSSL 0x0090701f

1 - OK It's not ssh it's ubuntu.

2 - I'll try this with ububtu.
...And by frozen, I assume ...
All Idle windows are unresponsive to screen and kbd events.

Please try two things:
1. Run IDLE directly on the ubuntu machine long
enough to assure there is no problem standalone.

2. Run IDLE on the xclient but start it with the
-n switch so it runs without the subprocess.

When IDLE freezes, walk over to the server and
kill the subprocess.  It should restart itself.  Is the
system still frozen?  And by frozen, I assume you
mean all screen and keyboard events are
unresponsive.

Yes, I've used Idle on that (although only ~ 1 hour) and not
seen the problem there.

Do you have physical access to the ubuntu warty machine, and
if so, does Idle run very well locally on that machine, not
X forwarded?

Yes, exactly. I'm pretty sure it's not an X/ssh/network problem,
everything else works fine (including Idle 0.8).

It has been a while since I ran Idle, but I am curious as to
what you mean by "run over ssh".

Do you mean that you have an SSH tunnel to a remote machine,
which forwards X-Windows sessions, and when running Idle
over this, it locks up?

PS - You don't need an editor window open to get the freeze.
