Also, check the trap destination configured on the device. If it's set to
the Xymon server, then look for a process on your Xymon server that's
listening for SNMP packets. On Linux, you can do "sudo netstat -naup |
grep :162" and it should show the PID and name of the process that is
receiving the traps.

(As David implied) neither does Xymon. There must be another process that
receives a trap and then generates a Xymon status message, but not
necessarily running on the Xymon server.
Googling the phrase ["Unknown trap" xymon] shows the HOWTO that David
linked to. I suspect someone has set this up on your Xymon server. This
means you probably have snmptrapd running, which you should stop if you
don't ever use SNMP traps.
