Hi Experts
I’m using net-snmp version 5.8 agent code to send traps, I implemented my own
trap sending code and compile it to a dynamic loaded object (myTrap.so), and
loaded in by putting configuration into snmpd.conf like this:
dlmod myTrap /usr/lib/myTrap.so
However, every time when I triggered the trap sending, snmpd got crashed, below
is the decode:
Program terminated with signal SIGSEGV, Segmentation fault.
