738.0. "monitored node crashed" by BACHUS::WILLEMSG (Geert Willems MCS-Belgium) Tue May 16 1995 16:05

    
    
    	Hi,
    	
    	Anyone has seen this before ?
    
    	Polycenter Console Manager V1.5a, OpenVMS V6.1.
    	This happened already inhouse (other departement then mine)
    	and at customer's site (production system of banking environment).
    	This is what a Digital Consultant told me.
    
    	Both have the RWMBX problem. What happended is that the 7000
    	systems monitored via PCM crashed. Nothing was written in the
    	system dump file. No CTRL/P was done...
    
    	Are there known problems that PCM sents a halt to the monitored 
    	console ?
    	The Consultant thought that this happened on customer's site
    	and also on his environment. 
    
    	Can this be true ?
    
    	Any help/feedback is welcome.
    
    	Thanks & Rgds,
    
    	Geert

738.1YOSSAM::PHILIPAnd through the square window...Tue May 16 1995 16:3213
Geert,

  I doubt that PCM told the system to halt.

  What I suspect happened is that as a result of the RWMBX, the managed
  system couldnt output to the console, so all the opcom messages got
  buffered in memory, when I have seen this happen in the past (when an
  LA120 ran out of paper) the system eventually crashed.

  Could this explain what is happening?

Cheers,
Phil
738.2Crashing reason knownKETJE::GEORGESWith Digital, NO problems ONLY Solutions.Fri May 19 1995 12:2533
    Hi Geert,


    for your info, already one of the 2 sites problems have been found and
solved, maybe two.

    The symptom was : VAX7710 rebooting WITHOUT crashing, this is due to a
power supply failure.  We replaced the module which managed the power
supply modules (named CCL) and everything seems OK now.

    For what concerns the customer problems, it seems that the RWMBX state
of the CONSOLE CTRL process forced the monitored systems to slow down and
to be blocked.  As nothing was happening on the 7000, it seems one operator
decided to press the famous CTRL_P key.  At the same time, the management
platform was rebooted, we then have no trace of this.

    Sure that this problem (the RWMBX) prevent my customer (having already
27 PRODUCTION systems managed) to trust in PCM.  He would like to go back
to VCS but... the VCS system has already been reused.

    I'm currently testing the 1.6-003, and will maybe install this version
at site, but ... I already had problems with it.

    It's a long time that I have not been forced to reboot so often a
management platform.



    Regards, Dominique.
