X windows closing abnormally on HP-UX 11.0

[Jean Mesquida_1]

Hi all,

Sometimes, on my HP-UX 11.00 L1000 platforms, the X windows containing HPTERM or DTTERM emulations close themselves without warning.

The only information I can read before the window closes is some strange characters (NUL, GS, ... : all of them taking the room of a single character) and two lines merged on a single one.

This behaviour is seen with "top" or "ls -l" commands after resizing the window.

The last CDE Runtime patch on these servers is PHSS_23797 from APRIL 2001.

Any help is greatly appreciated.
Jean

I'm haven't seen the problem myself, but I hope this comment helps a little :
Your CDE patch has already been superseded with PHSS_23800 (June 2001 Periodic patch).
But probably it's not CDE that is the problem. Check your X/Motif runtime, XClients and Xserver patches (PHSS_22948, PHSS_23823, PHSS_21814 are a start).
Check your shell patches (PHCO_19054 for posix, PHCO_19053 for ksh and PHCO_19435 for csh. They are probably already superseded).
There are also command patches for "ls" and "top". Maybe they solve something ?

Thanks for your answer, Wim.

I am using Posix Shell and the corresponding patch installed is PHCO_22537.

The problem does not seem to be related to any command as it occurs also with 'vi' for instance.
From time to time, one hpterm (or dtterm) window closes, even if no garbled characters appear inside...

Thanks for any further information.

Jean,

fyi : PHCO_23875 sh-possix patch fixes a problem with shell core dumps after recieving an early SIGWINCH during startup .... this maybe worth installing then ?

I've not heard of this either .... I'd suggest looking around for some further clues .... check /var/dt/Xerrors though it may not have anything helpful, core files, $HOME/.dt/errorlogs & startlog and /var/adm/syslog/syslog.log ... may also be worth your while running dr_dt ?

Thanks Alex.

I also noted this patch could be of some help : one of the symptoms described as corrected by superseded patch PHCO_22537 matches the behaviour of my dtterm windows (I am able to make them vanish by resizing them several - not 12... - times).
The problem is that PHCO_22537 IS installed on my servers...
I shall try and install the patch you mentioned.

BTW, I have not been able to reproduce the problem on hpterm.
Thanks again
JM

Do you find a "core" file in the directory where you were working at the time the window disappeared ? Or a core file anywhere on the system with a date/time corresponding to the time of a disappearing window ?
A command "file core" or "what core" can give you some information about the cause of the problem.
And for the rest, I have to agree with Alex : check /var/dt/Xerrors, $HOME/.dt/errorlog, /var/adm/syslog.log.
