Re:  .0

There are several bugs that can cause DECterm V1 to crash.  What were you doing
just before the crash?  Were you using ReGIS or sixels, or just text?

It's also possible that you ran out of some resource, such as virtual memory
(even though you said you have large values for your system parameters).  How
many DECterm windows did you have running?

It's unfortunate that the entire controller crashes when there is a problem in
one window.  There isn't much improvement for this in V2; maybe V3...

    I was not doing any graphics stuf.  I just had lots of text windows
    open logged onto many remote machines.  I don't think the problem is just
    related to having many windows open as I can get away with many windows
    for quite a while before this problem happens.
    Infact the problem has only shown up about five times since april.
    The problem always crops up while I execute a command of the form
    crt -sethost kopec
    where crt := $DBUGME$DUA0:[DEPLEDGE.XTOOLS]DECW$CRETERM.EXE
    crt is a command I use to create new windows that connect to remote nodes

        This problem has shown up on several other peoples workstations in
    my group.   They also get the crash while creating new windows.

Re: .2

Something else to be aware of is that there is a memory leak in DECterm V1:
it doesn't free fonts when you exit out of a window or change fonts.  If you
run the same controller over a long enough period of time (creating new
windows and/or changing fonts) eventually DECterm will run out of memory.

When you go home at night, try Quitting out of the session manager instead
of Pausing, and see if the problem goes away.  If not, you should probably
submit a QAR, but I'm not going to worry about it too much unless people
start reporting the same thing in DECterm V2.

At least once a week I get the following message in my session mgr. window:
"DECterm Controller process stopped: Message number 12DB821C
Started DECterm controller"

At this point all my DECterms are gone.

I always run with 3 DECterms.  I can't repeat the problem.  Sometimes I'm
just typing and other times I'm running a DECwindows application program.

    I also get this problem, at random intervals.
    
    I generally have 4 DECTerms running, linked to 3 hosts, and it's very
    annoying when they all disappear.
    
    Sometimes I don't get the problem for several weeks, then yesterady it
    happened twice in the same day, leaving the messages :-
    
    DECTerm controller process stopped : Message number 12DB822A
    Started DECTerm controller
    DECTerm controller process stopped : access violation
    Started DECTerm controller
    
    Can anyone give me any pointers ? Which system parameters should I
    start with ??

Re: .5

I don't think there are any parameters you can tweak to fix message number
12DB821C, but the accvio is often caused by GBLPAGES or GBLSECTIONS being
too low.

				-- Bob

    OK, I think it may have something to do with the PIC in DBQ, which is a
    Regis drawing. DECTerm doesn't seem to handle this too well - sometimes
    the text is missing unless you switch to another window then return,
    e.g.
    
    But I don't think it's the Global Pages / sections problem : I have 
    52398/27602 Global Pages Used/Unused, and 219/181 Global Sections
    Used/Unused. The DBQ Regis seems to take about 2,000 Global Pages.
    
    It seems to be happening when I shrink the DBQ window, do something
    else, then try to bring it back. Any more ideas ?

    I just got the Access Violation again.
    
    This morning I checked all the suggested parameters in 110, and mine
    are way above. I have around 450 spare Global Sections, 50,000 unused
    Global Pages, and my GBLPAGFIL is 22048.
    
    The problem always occurs when I'm using DBQ, though I always use SET
    NOPIC now, so it's not Regis-related. I had a DBQ window up and pulled
    another window up from an icon and all 4 DECTerms just disappeared.
    
    I'm pretty convinced now that it's a resource problem, but not GBLSECT,
    GBLPAGES or GBLPAGFIL. How can I find out which one it is ??

    I just quick checked, and no one really said what version this was.  I
    submitted a QAR for V2 EFT1 about all my DECterms disappearing with an
    access violation.  I was lucky enough to find a traceback for it.  The
    answer was "fixed in V2 FT2", and I've been running FT2 since last Friday
    with no problems.

    Looks like I'm running V1 FT2 (I'm on VMS V5.0-2, and the DECWindows
    images have an id of "DECWINDOWS FT2").
    
    To get the latest version I guess I have to be on VMS V5.2 ? And until
    then I just have to live with the problem ?
    
    OK, sorry for clogging up your conference ....

    You can get the SSB version of DECwindows V1 with VMS V5.1.  If you
    want the latest V2 FT version of DECwindows, then you want VMS X5.3.
    I believe that VMS V5.2 only had some DECwindows V1 bug fixes in it.
