I'm running LTSP 5.2.1 under Ubuntu 10.04 with 9 frontends and in the
last few months there is one frontend which is freezing within the GUI
(Gnome2) about once a day sometimes. What I mean by frozen is, we can
move the mouse but not use the keyboard and cannot click on any window
or menu within the system. I cannot jump to a virtual terminal using
<ctrl><alt><F1> or any other VT.
Here is what I've tried (in order and the problem still exists after
each change)
05/03/2013 - Swapped hardware
- [X] Change over network switch with new
- [X] Change over thin client with a known working thin client
06/03/2013 - Froze
- [X] Change port used on wall plate to the new network switch
(This involved switching the cables in the patch panel around so
different patch cable is used here).
- [X] Change cable from Netgear 5-port router to wall plate
- [X] Change patch cable used for terminal
07/03/2013 @ 8:20 - Froze
- [X] Swap Red cable between Netgear router & thin client.
22/03/2013 @ 11:45 - Froze
- It showed up disconnected in Epoptes, but I could still get the IP &
connect via SSH
- I could reboot the machine over that ssh link.
So I've changed all the cables between the server and thin client now
and the actual thin client itself. I've changed the switch that was used
next the thin client.
When I ssh into the thin client whilst in it's 'frozen' state I can see
that Xorg is using 100% of the CPU.
What else can I try?
There is nothing obvious in the syslog or messages log, are there other
log files or ltsp specific logs which I should check?
