CDE hangs intermittantly

Rajesh Tarkunde — Tue, 04 Jun 2002 10:44:15 GMT

Hello
I have HP 9000/735 machine with HPUX 10.2
The CDE on this machine just gets stuck up intermittantly.
I have to telnet the machine and kill the process /usr/bin/X11/X :0
After doing this I get the login prompt but loose the earlier data on the screen.
Can anybody tell me what to do ?

Thanks in advance

Rajesh

Rajesh,

I'd seriously consider installing HP-UX 11.?. At the very least, you probably need to bring your patch levels up to date.

HTH,
Pete

Hi

Indeed probably patches

However

/var/dt/Xerrors
$HOME/.dt/errorlog

Do they contain messages.

Xconfig

If not in /etc/dt/config then copy from /usr/dt/config

This file contains timeouts which can be raised for things like NFS

I'd check to see if there are any patches. Update to the current patch bundle or use the custom patch manager.

While patches are good thing to check, here are some methods to distinguish if the problem is with the Xserver or with CDE itself...

11.00 may not be appropriate for a 735, depending on the graphics card. 11.00RelNotes in /usr/share/doc have info on graphics cards that went out of support life.

Does the mouse pointer move at all? Can you telnet to the system and do xclock -display :0.0 and see xclock?
If you can, then the Xserver is functional, and it is CDE that is having problems.

Look in /var/dt/Xerrors, $HOME/.dt/errlog and startlog.
Possibly patch CDE

If the pointer DOESN'T move, then it indicates that your Xserver is having problems. Check to see if /usr/bin/X11/X is consuming cpu.

Next step would be to look for Xserver patches.

Stack trace might be able to isolate what defect the Xserver is suffering from.

- touch /core
- chmod 666 /core

Then, when the Xserver is 'stuck', do a kill -6 to the pid of the Xserver.

Look at the stack trace with:

gdb /usr/bin/X11/X /core
(gdb) bt

If you get to this point, you'll probably need to log a support call.

Rick is right about the appropriateness of 11.x on a 735. It would probably work (I've loaded it on old 715 with no problems) but it's not supported. See:
