3671.0. "VMS5.4 and DECwV3 crashing on low memory machines?" by GALVIA::BVANLEW (Look for a tank, with the moon in your eyes...) Thu Nov 15 1990 09:38

    We have a largish cluster (2x 6430 + 50 workstations)
    running VMS 5.4 and DECwindows IFT3.
    
    A vaxstation 2000 with 6MB memory and a 3100 with 8MB
    memory crash when multiple windows applications are
    invoked.  By multiple I mean - 1 DECterm,1  DECwrite
    and 1 CDAviewer.
    
    Setting bytlm, prclm, and pgflquo to higher values
    have all been tried without success.
    
    None of the log files show any errors.
    (decwindows server log and the system error log)
    
    Could the crashes be related to the 'small' memory
    on both machines? Other workstations in the
    cluster have a minimum of 14MB?

    Try George Claborns Memory Mgt. stuff, details of which are outlined in
    a topic I enetered here last week.

    It's note 3590 (I'd missed that one).
    
    I'll give a whirl!
    
    Thanks Andy.

    re: .-1
    That doesn't answer the question of why small memory systems crash.
    It should be QAR'd with appropriate info to track it down.
3671.4Will QAR shortly...GALVIA::BVANLEWLook for a tank, with the moon in your eyes...Fri Nov 16 1990 11:4724
    Due to a variety of problems on our cluster it will
    be 'rolled-back' to V5.4 and DECW-V2.
    
    At the moment it's difficult to tell what things are
    being caused by V5.4 and what by V3 windows.
    
    Once this has been done I'll submit a QAR on the problem.
    It will be possible to give a clearer picture of what's going
    wrong.
    
    By the way, George Claborn's Auto-Tuning Memory Management
    software did make a difference.  It was possible to start
    the applications I named in the base note, on the 3100.
    (Didn't get a chance to try the VS2000)
    
    However it wasn't bomb proof.  If several applications
    were started in quick sucession (by Automatic Startup)
    the window manager died.
    
    I'll see how things look on Monday with V5.4 and WIndows V2
    and submit a QAR then.
    
    Regards,
    Baldur

    re: .3
    
    I know, Jeff, just trying to quickstart the person with the problem.
    
    Certainly needs a QAR.
    
    Frankly it's getting toward time that the memory needs of DEv3 are
    defined for the SPD. I *bet* it takes more. (Just a hunch)
