By executing the command
snmpbulkwalk -C r240000 192.168.103.94
I was able to bring a fellow developer's system (running Linux 2.4.25 on a Power PC) to a stand-still as the SNMP agent (version 5.4) consumed all available memory and CPU trying unsuccessfully process the request.
This problem report resembles report 1206723, which appears to have been summarily closed without resolution. I would guess fixing this problem should be as simple as capping max-repeaters to some reasonably small value (aiming for a limit of, say, 16 Kbytes, perhaps).
