4372.0. "remote X and MAP problem" by ANOSWS::COMFORT (Cold iron shackle, ball & chain) Mon Jan 11 1993 12:56

    
    Hi,
    
    I would like to ask if anyone has  seen the following behaviour around
    the DECmcc Iconic Map PM.
    
    We have a VAXstation 4000 mdel 60 w/ 104 meg memory.  I run detached
    MCC and two exporter jobs and ~170-200 rules, 150 or so of which are
    polling rules running every 5 minutes.
    
    When we boot up the system, I submit two batches that bring up two maps
    (the system is dual headed), each opening a different domain.  Then
    various persons will submit batches that create a map window on their 
    workstation, be it a PC, Risc/Un*x or VAX.
    
    This works great, we can get 6 maps or so running before memory starts
    to become an issue.  And the system will hum along for a week or two. 
    Eventually, the remote maps get disconnected, especially by PC that get
    shut off, so one will have to re-create the Xdisplayed map.  What
    happens is that without warning, Xdisplays of the map will not happen. 
    The network link comes up, the man/ent/int=decw process shows 10s of
    thousands of I/Os and page faults and everything appears to function
    normally, except no map.  Other X applications work great, ie. Clock,
    Cardfiler,  Create/Term/Detach.  The only way to correct this situation
    seems to be a complete system reboot.  I have tried restarting
    DECwindows, to no avail.  When this does happen, entering line mode is
    still operational.
    
    Any one have any ideas?
