    Cluster of 4100 and 3 76XX
    2 76XX and 4100 share common system disk
    1 76XX separate system disk
    AXP VMS V6.2-1H3
    Decnet/OSI V6.3 ECO5
    X.25 V1.0E
    
    1 76XX crashes on shutdown. Customer believes that it always happen.
    Problem does not happen on the other systems.
    I searched CANASTA but no previous reference.
    Crash dump available. 
    Fixed in ECO6?
    IPMT time?

If you want someone to look at this I suggest you lodge an IPMT
against DECnet/PLUS and supply a pointer to the crash dump.

The fact that X25$DELETE_ENTITIES was running at the time of the
crash does not imply this is an X.25 problem. DECnet's NSP
generated an access violation, so DECnet should look at it first
and they can get X.25 help if they need it.

IPMT already logged and fix provided by Decnet/Plus engineering.
Fix is in NSP.
