Default snmpd hangs/loops on FC3 and RHE4

Hello all,
I'm having a problem on all Fedora Core 3 and Red Hat Enterprise 4
systems that have net-snmp-5.1.2 installed. It seems that after some
random amount of time, the snmpd daemon stops responding to snmp
requests. After browsing through the list archives, I found a
suggestion to run the following command:

snmpd -f -Le -Dall

After several minutes and thousands of log lines later, I see that some
sort of loop starts occurring. Below are some normal outputs of snmpd
as it responds to some GET requests, and then the "loop" begins.
Basically, when this loop begins, it just goes on and on forever. I
have a SecureCRT session log that's over 100MB in size thanks to this!

If anyone knows what the problem is and how to fix it, I'd greatly
appreciate it. Red Hat support won't help me any further with this, so
this is my final hope. Also below is my snmpd.conf file.
