That's what it sounds like to me.

What version of trap are you generating?  I.e. do you have a 'trapsink',
a 'trap2sink' or an 'informsink' directive in the config file?
   The UCD master agent currently doesn't generate legal SNMPv1 traps
when they're received from a subagent.   It does send them out, but with
a generic trap value of "-1".   The UCD trap handler is sufficiently
forgiving to accept these - it may be that the commercial product is
more strict.

  Try configuring with 'trap2sink', to generate (valid) SNMPv2 traps.

  I'd hoped to be able to fix this problem before the release, but I think
time's probably running out on us.
