Hi.
Have all your tests been with the same trap? If so, can you try a different trap such as a coldStart?
Try configuring snmpd on the machine with:
trapsink 127.0.0.1 public
and then restart snmpd. You should get a coldStart trap.
Another thing to try is to DELETE your snmptrapd.conf file and re-create it from scratch. Probably unlikely but invisible escape codes have caused me problems many times (not necessarily with Net-SNMP).

HI Thomas,
I have some more information on the problem as I have been working on this all day today. To anwser some of your questions first:
1) No this displays the same result
2) I have checked with ps and the process is missing after I receive a trap it dies
3) I have performed an strace and it seems as though it is getting a SIGPIPE (Broken Pipe) signal
Here is some of the output of the following command:
strace /usr/local/sbin/snmptrapd -n -Lo -f -On -C -c /usr/local/share/snmp/snmptrapd.conf

- I have tried running this on Fedora Core 2 with the exact same results :(
Thanks very much for your response!

I was using net-snmp 5.1.1 but then prayed and hoped that if I compiled
and
installed 5.1.2 the problem would go away, so now I am using net-snmp
5.1.2
and still having this problem.
Do you have the chance to check if you also see this problem with 5.2.rc1?
Also, a few other ideas: - Does env SNMPCONFPATH=/usr/local/share/snmp \ /usr/local/sbin/snmptrapd -Lo -f -Dall -On work any better for you? - Have you double-checked (with ps or pgrep) that snmptrapd has really exited? - You may want to run snmptrapd under a debugger to see where/why it exits
