Environment

Component : Spectrum Core / SpectroSERVER

Resolution

Stop / Kill the SpectroSERVER

Change the snmp trap port = from NULL to 163 in:

$SPECROOT/SS/.vnmrc 

Initialize to legacy

cd $SPECROOT/SS/

../SS-Tools/SSdbload -il legacy.SSdb

Then load a good know SSDB backup

cd $SPECROOT/SS/

../SS-Tools/SSdbload -il {db_XXXXXX_XX_XXX}.SSdb

Restart Process Daemon

cd $SPECROOT/lib/SDPM
./processd --restart

Start Spectroserver

Now spectroserver will be stable but it will not process the traps.

Find out which devices are sending Trap Storm, either delete those device(s) or remove the trap_destination on the device to this spectroserver

Now change the snmp_trap_port=  (Blank)  in $SPECROOT/SS/.vnmrc

Stop Spectroserver
Restart process daemon
Start Spectroserver
