Problem with graph monitor when many grass users on one computer

[Hans Hauska]

I have recently installed Grass4.1 on a Convex C3220.
Everything seems to work fine, except that the graphic
monitors get hung when I run whole labgroups with 
10-13 X-terminals.
I tried to duplicate the XDRIVER and attach only up to 4 
monitors to each copy of the driver, but unsuccessful.
Is there anybody who has experience in running simultaneous
ten grass sessions from one computer?
All suggestions are welcome.
