Hi Thomas,
Had to get gdb compiled on the box so it took a bit longer than I liked
to get back to you. Here is the backtrace. Recall the snmpwalk that
causes the SEGFAULT is:
% snmpwalk -v1 -cpublic sys01 .1.3.6.1.2.1.25.1
HOST-RESOURCES-MIB::hrSystemUptime.0 = Timeticks: (1841499111) 213 days,
3:16:31.11
Timeout: No Response from sys01
Backtrace:
