I was able to make it core dump by running an snmpwalk on the entire
tree. I was running both a snoop (port 161) and a truss (on snmpd) at
the time.
The output of the snmpwalk was:
bash-2.05b# /opt/net-snmp/bin/snmpwalk -c bti2snmp$ smtp1
. . .
RFC1213-MIB::ipAdEntAddr.216.235.160.75 = IpAddress: 216.235.160.75

RFC1213-MIB::ipAdEntIfIndex.216.235.160.75 = INTEGER: 2

RFC1213-MIB::ipAdEntBcastAddr.216.235.160.75 = INTEGER: 1
Timeout: No Response from smtp1
Here is the last of the output from truss:
getmsg(13, 0x00000000, 0xFFBF46C8, 0xFFBF46C4) = 2
getmsg(13, 0x00000000, 0xFFBF46C8, 0xFFBF46C4) = 2
getmsg(13, 0x00000000, 0xFFBF46C8, 0xFFBF46C4) = 2
getmsg(13, 0x00000000, 0xFFBF46C8, 0xFFBF46C4) = 2
getmsg(13, 0x00000000, 0xFFBF46C8, 0xFFBF46C4) = 2

getmsg(13, 0x00000000, 0xFFBF46C8, 0xFFBF46C4) = 2
getmsg(13, 0x00000000, 0xFFBF46C8, 0xFFBF46C4) = 0
Incurred fault #6, FLTBOUNDS %pc = 0xFF2CB12C
siginfo: SIGSEGV SEGV_MAPERR addr=0x00126018
Received signal #11, SIGSEGV [default]
siginfo: SIGSEGV SEGV_MAPERR addr=0x00126018
Does this shed any light on the situation?
Still confused,

Thanks for the suggestion. I've got one of the instances of snmpd
running under truss. If it crashes tomorrow, at least I'll be able
to see what it was doing at the time.
I'd also run snoop on port 161/udp on that machine to possibly see the
packets that caused this. Do you by chance have an enterprise NMS that
starts an inventory at 7:30 am?
