CDE/X/Display goes blank

[Sharath_2]

Hi,
I am running HP-UX 11.0 on B2650 workstation. We are running high end CAD/CAM/CAE software like MSC Nastran, Catia V4 on this machine. Sometimes when a user invokes any Catia/Nastran file, the display completely blanks out. Don't know if this is bug in X/CDE software? The only way to recover is to reboot the machine by logging in remotely and giving the reboot command. Any ideas?

thanx,
Sharath.

yes prior to rebooting examine contents/output from top ... any zombies or processes eating cpu ? eg CATSTAR

any clues, core file produced or entries in /var/dt/Xerrors

consider toc'ing the box to create a crash dump
for futher analysis

run dmesg ...any errors ?

Patch level wrt cde,Xserver opengl etc ? swlist output would be useful.

Also please let me see output from graphinfo.

Lastly I take it you have tuned the kernel as per CATIA's installation guide or similar ? how long has this been occuring , suddenly started ?

Hi


Alex gives good advice

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

Also /var/adm/syslog/syslog.log


When you login to reboot do first a
ps -ef|sort -n and save the output

file core of any corefiles found

Post it all
