Hi Bryn, would it be possible for your to run rsyslog with valgrind? This would be very helpful.
I just have run a short test with your config snipset on my testmachine, and it works well and is sending snmp traps. So my guess is that there is something wrong with the net snmp libraries, or something is missing.
