9374.0. "triple headed display open problems.... 55050" by finder.uvo.dec.com::COFFEYJ (La Feline Flooz - a unix cat) Thu Apr 03 1997 05:23

I have a customer who gets an error opening 
the display on his triple headed workstations 
intermittantly - any suggestions appreciated!

They have an alpha server 400 4/233 running digital unix. 
Motif version 1.2 (they're not sure if it has any patches) 

It only happens on the tripleheaded workstation and only if it's 
trying to load a large diagram with a lot of traffic. 
It only seems to happen with respect to screen 2, where it triggers 
a segmentation violation, if they set it to setup screen one completely, then 
go on to screen two's setup then it's ok. 

They think it may be a timing problem and would like to confirm what the 
meaning of message was and what was likely to have created it.

The message is: 

Xtoolkit warning: name millenium(app) class xmdisplay unable to open display

and this was happening whilst it's trying to fetch a text field with
Mrmfetchwidgetoveride.

They think it to be timing related because the application is kicked of as part of
the login.  They have orbix running and the launcher program is kicking off the
application which they think is getting the error. 


Like I said - any suggestions welcome..... 
(dpyinfo attached too) 

thanks 


Jo.
