I see snmpd die with that message fairly often (about once per a week)
on one 1.6.2 box which is measured by mrtg. I haven't seen that problem
on another 2.0.2 box also measured by mrtg.
By chance, aren't you using net-snmp compiled for some previous major
release? net-snmp uses KVM routines, so it's very sensitive to kernel
structure changes. Compiling with userland up-to-date to the running
kernel might fix your problem.
