dtsession memory fault

Viktor Holmberg — Thu, 10 Jun 2004 18:48:52 GMT

Hi There,

I have probelm that is driving me mad.

We currently use VNC and eXceed as xservers in our environment. I just recently reinstalled one of the servers to 11i Dec 2003 plus a bunch of extras patches. Nearly the same as its cluster friend. The install went 100% ok.

Now when I start a vncserver session as root everything works OK and I have a proper work cde enviroment. If I do it as any other users, vnc starts OK and I can connect and puch pack Xterms, but dtsession refuses to start, it memory faults. /usr/dt/bin/dtsession has setuid for root set, and if I remove it, dtsession comes up but with some expect permission problems.

Anybody got any ideas why dtsession memory faults ? I have had similar problems with other programs in the past and it been and environment variable issue but I can not see it this time.

Thanks

Viktor

in /etc/profile

env > $HOME/env.txt

log on dt as root,

then another user

compare the two files.

Something is different.

I suppose it could be permissions, but your are a good admin, and you'd know if permissions were manually changed.

Good luck,

post anything you find.

hi Viktor,

could u also send $HOME/.dt/errorlog as well?

also, any log in /var/dt/Xerrors?

regards.

There are no entries in either of those files. I presume dtsession crashes out before ut haas a chance to do any thing.

I have cheched dr_dt apart from a couple of warning that I have check it reports nothing exiting.

The speed of which dtsession memory faults indicated that it is not getting very far at all.

hi,

could u produce the output for the following:

# ps -ef | grep rpc
# ps -ef | grep dt
# rpcinfo -p

also u may like to restart CDE, but note that each user should be logged out of the system before executing these commands:

# /sbin/init.d/dtlogin.rc stop
# /usr/dt/bin/dtconfig -reset
# /sbin/init.d/dtlogin.rc start
# /usr/dt/bin/dtconfig -e

regards.

Hi There,

I have solved the problem with the use of good old truss.

The problem was introduced by patch PHCO_20530 (lic cummulative patch). The patch introduces a problem with suid and sgid related to NLS and inparticular /etc/default/nlspath. The solution is either to put the message files in the NLSPATH or a * to invoke the old behaviour.

At the time of download there was no warning posted against the patch. But now there is ;-{

Thanks for all your help,

Viktor
