I have found a solution to this problem.
Solution:
------------
If I comment out snmp_shutdown from the steps that I have mentioned before,
the trap will be sent properly all the time.
That is, if snmp_shutdown() is not called after sending trap, then
snmp_add() doesn' t throw any error the 2nd time an attempt is made to send
another trap. Looks like snmp_shutdown() was doing something nasty which was
preventing the session from opening again.
But I am not sure whether not calling snmp_shutdown() after sending the
trap(and closing the session using snmp_close() ) is the right thing to do.
Can anyone please let me know whether there will be any side effects (memory
leaks etc) if we dont call snmp_shutdown() at the end of the application? Is
invoking snmp_close() enough to do all the clean up?
Thanks
