3423.0. "Disappearing MCC.." by SIOG::TINNELLY (Consultancy for fee NOT free..) Fri Jul 24 1992 08:50

    
    Hello Folks,
    
    I have recently installed the V1.2 DECmcc ULTRIX kit, I brought it up
    OK, and initially was getting MUNLOCK Panic crashes. I have applied the
    patch as documented in the release notes, and rebuilt the ULTRIX
    kernel - no problem.
    
    I broght DECmcc up again and was in the middle of VI editing an
    autoconfig file, when all my MCC screens disappeared from the screen.
    
    It reported the following error back to me:
    
    Sendsig: cant grow stack PID 207, PROC MCC_ICONIC_MAP_PM
    Illegal Instruction.
    
    I noticed in section 3.1.1 in the release notes it indicates that there
    are other patches available to mitigate existing problems.
    
    Have I hit one of these problems. Where do i get the patches??
    
    many thanks 
    
    Peter.

3423.1Swap space?TOOK::MINTZErik Mintz, dtn 226-5033Fri Jul 24 1992 10:389
Actually, this sounds like a resource problem (might you be running
out of swap space?)

As for ULTRIX system patches, customers get them from the CSC.
Internal users should probably check the ULTRIX notes conference to 
see if there is a pointer to an Enet distribution point for them.

    Erik,
    
    I have checked the Swap space, and have 93 MB of swap space total with
    almost 47MB Free. Should be OK. Thinking about it I will not be using
    the processes mentioned in the release notes,as my frontend is a VMS
    w/s. I will check the patch kit for ULTRIX anyways.
    
    regards Peter.
3423.3did you `source mcc_login.csh'?KAJUN::NELSONMon Jul 27 1992 10:5117
Sorry if this suggestion is too obvious, sort of like the maintenance 
person making sure that the device is plugged in.  You are running out of 
stack size and I know that the mcc_login.csh or equivalent shell script 
for your shell sets the thread stack sizes.  Did you `source' the .csh
file before you brought up the IMPM? 

The IMPM runs multiple threads.  And the child threads get created with 
the stack sizes determined by mcc_login.csh.  If you do not `source' the 
mcc_login.csh file the threads are brought up with a default stack size 
that is too small for some MMs.

You can check the stack sizes by `saving' your current settings using 
the customize menu of the IMPM.  Then look in mcc_resource.dat for the 
stack sizes.  Better yet, just make sure each user `source's 
mcc_login.csh.

3423.4Stack sizes look ok.SIOG::TINNELLYConsultancy for fee NOT free..Tue Jul 28 1992 07:1511
    
    Hi,
    
    Dont worry about asking the obvious question, I am a novice ULTRIX
    user so it is quite possible that something basic at the ULTRIX end is
    incomplete. 
    
    Regarding the Source mcc_login.csh, that has been done, and when I do a 
    Setenv command I can see the various stack sizes ok.
    
    regards Peter.
