I am not familiar with "nimbus", but it seems like it is listening on port 162. You cannot have two things listening on the same port... You will have to remove nimbus from your system, and try restarting snmptrap again.

I need to remove nimbus snmp service out to avoid the conflict on upd 162
/opt/Nimsoft/bin/niminit stop
/opt/Nimsoft/bin/inst_init.sh remove

[lmiltchev]

Let us know if you are able to start snmptrapd service after removing nimbus. Thank you!
