I'd strongly suggest that you upgrade to 5.2.2, or 5.3.0.1.
The 5.0.x line is extremely old code now, and things have
moved on a lot since then.

Why do you want to send *two* copies of each trap to each
of these destinations?  Please use *EITHER* "trapsink" *OR*
"informsink" for any given host receiver.  Not both.

--Thanks, I've removed the 'trapsink' lines. Just to confirm, the remaining 'informsink' lines will send all generated traps to the specified destinations?--

That looks good.
Presumably you also have a "createUser internal ..."
entry somewhere?

--Uhmm, no. The file I listed in the original email was complete. I've now added the line "createUser internal MD5 "<some phrase>"" to the snmpd.conf file just above the "agentSecName" line. Is that all that's required? I've tested this new configuration and am still not generating traps for process problems.--

What do you see if you walk the usmUserSecurityName object?

--"internal"--

What do you see if you walk the prTable?  Has the corresponding
prErrorFlag been set?

-- Yes, the prErrorFlag is being set and cleared properly for the specified process, just no traps.--

Try running the agent with '-Dmte' - what debug output do you see?

--I'll try that and let you know.--
