DECWindows crash when starting Mozilla

Christoph Gartmann — Thu, 29 Sep 2005 10:20:58 GMT

When a user starts Mozilla the DECWindows server crashes.
OpenVMS 7.3-1, Mozilla 1.7, DECWindows 1.2-6
DECW$SERVER_0_ERROR.LOG shows:
Fatal server error:
Server restarted. Jumped through uninitialized pointer?
This happens with every user. The node where it happens is an AlphaStation 255 with 512 MB of memory. It is part of a homogenour cluster. There is no such problem with the other nodes (but these are different models).
System paramters conform to the DECWindows requirements as stated in the installation manual. Other windows applications work. Any ideas on how to proceed?

it could be a resource problem on that node. Has it previously worked and do the system parameters and user quotas confirm to the recommded values?

We never tried Mozilla before on this node.
The user quotas should be ok because the users are all able to run Mozilla on any other node. System quotas conform to both, DECWindows and Mozilla. I assume that some system parameter might be wrong. But how can I find out which one?

Christoph,

I think you should log a case with your local HP Customer Support Centre. This type of problem isn't really suited to the forum mechanism. Too many branches in the diagnosis decision tree.

If you are running the hp packaged version of mozilla and have vms support then you can ring your local hp support centre.

I do have VMS support but I am not sure Mozilla. It was packaged by HP as a PCSI kit but it is normal Mozilla and not the Secure Web Browser.

Here is some additional info:
I compared the DECW$SERVER_0_ERROR.LOG with the ones from other cluster nodes. I noticed the following fault (independent of Mozilla):

tm_device_init: Drawlib not loaded.
PexExtensionInit: DD_DEVICE_INIT failed
glScreenInit: Drawlib not loaded.
GLExtensionInit: glScreenInit failed

What does this mean? The graphics card is a PBXGB-CA (PowerStorm 4D20).

Now I solved the problem: in DECW$PRIVATE_SERVER_SETUP.COM the node had a
decw$server_default_visual_class of "3". Now that I changed it to "4" Mozilla is working.
Nevertheless the strange error in the server logfile ("Drawlib not loaded", etc.) remains.
I wonder what it means and how I could eliminate it.

Christopher,

I believe that this is part of the OpenGL Xserver extensions.

If you don't have a Open3d license installed, then the extensions don't get loaded and the Drawlib stuff is bypassed putting the graphics card in 2D mode.

It's a non-fatal error and you can safely ignore it.

There is an Open3D license installed:

$ sho license open3d/ful

Active licenses on node MPI6:

OPEN3D
Producer: DEC
Units: 0
Version: 0.0
Release Date: 30-SEP-1997
Termination Date: (none)
Availability: 0
Activity: 100

The license could be one that is transferred from an old system.

Is open3d installed ?
$ dir sys$update:open3*.vmi_data

Now I realized that I have version 4.9 of Open3D installed but that there is version 4.9B. Now that I have upgraded the error disappeard.

$ decw$server_default_visual_class == "4"
in DECW$PRIVATE_SERVER_SETUP.COM for the 4D20.

Upgrade from Open3D V4.9 to V4.9B to remove errors in DECW$SERVER_0_ERROR.LOG.
