4862.0. "Exception encountered on Phase V event notification.......hogs system!" by LICAUS::LICAUSE (Al Licause (264-4780)) Mon Apr 12 1993 13:37

I'm running V1.3 SSB DECmcc BMS on a V4.3 ULTRIX system with V5.1 DECnet/OSI.
The system is a DECstation 5000/240 with 128MB of memory.

When I attempt to create notification events for entity NODE *, the event
is created and enabled w/o problems.

As soon as I turn on a remote systems EVENT DISPATCHER OUTBOUND STREAM to
connect to this system, dozens and dozens of windows are displayed, each one
on top of the other indicating "notification request # for domain ....
encountered an exception".

So many of these windows are created that the workstation hangs until I can
login from another system and kill the mcc_iconic_map process.  

vmstat 3 shows that memory is being used up very rapidly and idle cpu = 0.

I did increase the system parameters as identified in the installation manual
and rebuilt the kernal.  dbx was used to verify that the new values have
taken.


I'm new enough to ULTRIX to know that I've hit my window of expertise.....the
above system information was obtained with the help of the CSC.

Don't know where to look next......

Any help greatly appreciated.

4862.1NODE * ANY EVENT alertCTHQ::WOODCOCKMon Apr 12 1993 17:5915
Hi Al,

I can't help with the exception messages but I can tell you what your 'next'
problem is going to be :).

Once you get by the exception problem with the help of someone in the know,
if you     NOTIFY DOMAIN x NODE * ANY EVENT    I'll be real interested to see
what happens to your CPU. When we did this the CPU went straight to 100% (back
in V1.2) because it seems to constantly check for all the events of the entire
entity model (hundreds maybe??). Maybe MCC has changed something for V1.3 to 
alleviate this but I've yet to try it with this version, but if not be careful
when using "*" and "ANY EVENT".

cheers,
brad...
