DISPLAY and XSTATION variables become unset for Xstations

[Paul Viscuso]

We recently installed the 3005 upgrade to our RS/6000's (model 530s).  Every once in a while, when someone goes to log in at an Xstation, the DISPLAY and XSTATION environment variables are lost.  When they type xinit (or whatever other script they have to start up the window manager), DISPLAY is set to unix:1, and so mwm is started up on the console.  The users don't have the variables hard coded in their .cshrc or .login files.  Has this happened to anyone else?  This seems to happen usually after the Xst






ation has remained idle overnight.  Any ideas would be appreciated.
