XtAppMainLoop () X-motif call is dumping core file.

[Sup]

Hi,

One of our program is dumping core file at
XtAppMainLoop (), Is there any patch available?
gdb backtrace is

Hi,

You never specified which version of HPUX you are running?

I don't think its XtAppMainLoop() that is causing the problem - I think its mallinfo(). See the libc cumulative patches for details :

PHCO_25640 s700_800 10.20 libc cumulative patch
PHCO_27731 s700_800 11.00 libc cumulative patch
PHCO_25883 s700_800 11.00 cumulative 10.20 libc compatibility support
PHCO_27910 s700_800 11.11 libc cumulative patch
PHCO_25898 s700_800 11.11 cumulative 10.20 libc compatibility support

The patches mention this can happen when memory is tight - run "vmstat 2 5" and check how many "free" pages you have.

regards,

James.

Hi,

Thanx for reply. Hp version is

$uname -a
HP-UX proof B.11.00 E 9000/800 615399383 8-user license

From the stack trace, I would suspect that you are trashing memory. While this could be a problem witht he library, it could be a problem with the application. XtAppMainLoop() is probably not responsible.

It does look like you are in the middle of a drag and drop operation:

_XmSetDragReceiverInfo () from /usr/lib/libXm.4

If your app doesn't require drag and drop, you can disable it via resources (man XmDisplay).

On the other hand, I would make sure that you have up-to-date patches for the Motif runtime.

I'm suspicious about the thread code. Is the app threaded?

Hi,

Thanx for the response.

The application is not threaded. We added memory to this machine and still getting core dump at same place.

This is how it core dumps
1> Run app to open a GUI.
2> As soon as we select menu item which
displays list of items,it core dumps!

Any suggestions?
