[FreeNX-kNX] Crashes when closing an application

[Alex King]

I am running a server system on Debian stable (Lenny), with freenx server
packages from the Ubuntu PPA (0.7.3+teambzr104-0freenxteam1~intrepid1).

The clients are the nomachine 3.3.0-6 debian package running on Debian
stable.

I am having a problem that when some particular programs are exited, the
whole session crashes.  This happens consistently when a particular windows
program is run under wine, and also often with openoffice.org (Debian
backports version 1:3.1.1-1~bpo50+1).

With the wine program, I have told users to minimise the program instead of
exiting it, and this is a reasonable short-term workaround.  It is
impossible for them to keep open every openoffice window they use though.

After the sessions crash, subsequent logins often have problems starting
gnome-panel or nautilus, and we have to kill and restart them to get them
working OK.

There appear to be few clues left in the logs - the users' xsession logs
show the x server has gone away.

The following message appears in the nx log:

1004 Error: NX Agent exited with exit status 1. To troubleshoot set
SESSION_LOG_CLEAN=0 in node.conf and investigate
"/home/marilyn/.nx/F-C-cushn14-1025-B46698BBE414DD5A651FB3B3E242892C/session".

I have done that but I can't see anything there to help me.

If I bypass nx altogether by using xdmcp logins, everything works fine
without the crashes.

How should I go about debugging in a situation like this?

Cheers,
Alex
