Hi,
This bug is currently closed but I have experience the same as the bug reporter and I can reproduce the problem.
I have posted comments to the bug entry including work around. (See below)
I don't think this is related to bug 930993 because I have applied the change to the source on ver 5.1 suggested in the bug's comment and the problem still occurs.
Many thanks Joe

I agree with cfmartin. The problem does exist, even I invoke the script /etc/init.d/snmptrapd, not from inittab.
You don't see the problem probably because u do /etc/init.d/snmptrapd start FROM COMMAND LINE.
We have a daemon running and calls /etc/init.d/snmptrapd to start, it immediately consumes over 90% CPU and floods the log file with repeating messages:
Connection from callback: 1 on fd 2 pdu failed to be created
The log file accumulates 1 GB per day.
The daemon is programmed in C and calls system('/etc/init.d/snmptrapd start').
The problem disappears if you do /etc/init.d/snmptrapd start from command line.
Our system is running SUSE (SLES) 9.1 with net-snmp-5.1-80.11.
I have also tested with building from 5.1 source.

Gotcha!!!!!
One of the difference between command line and invoked from another programme is the fd 0 1 2.
If you change your snmptrapd init script of line
startproc $SNMPTRAPD -c /etc/snmptrapd.conf -Lf /var/log/net-snmptrapd.log
to
startproc $SNMPTRAPD -c /etc/snmptrapd.conf -Lf /var/log/net-snmptrapd.log > /dev/null 2>&1
The problem disappears.
