Hi all,
I have a trap callback function that checks the trap name against a list
of predefined names and resend the traps to other hosts if the trap name
matches a name in the list. This seems to work properly and I receive
the forwarded traps on the received hosts with the correct trap names
and values. In my test, I generate a trap every 5 seconds or so, after
about 40 traps are forwarded, the agent seems to exit without a core
dump.
This is the gist of my code:
snmp_sess_init( &session );
session.peername = "172.30.250.211:162";
session.version = SNMP_VERSION_2c;
ss = snmp_sess_open( &session );
snmp_sess_send( ss, pdu ); // pdu is passed in the callback
snmp_sess_close( ss );
The message log from the agent seems to indicate that the crash
occurred at the malloc call in _copy_varlist() where malloc returned a
bad pointer (not NULL).
I have tried to use the traditional snmp_open/snmp_send/snmp_close with
the same result.
Can you please give me some help with this problem. Is it legal to
resend traps in a trap callback function? Did I miss some important
setup/cleanup call in my code?
Thanks for your help.
