Dear All
Happy new year to all of you.
I am running net-snmp 5.4 on RHEL 4.0 64 bit OS. I have been seeing the
subagent crashing sometimes while sending traps.
The stack trace is as follows:
(Please let me know if you any questions in understaning the problem)

---------------------
Looks like, there is some corruption happening. I am quite not sure how to
catch this kind of thing. In function#3 above, I see that values for trap and
specific are -1, but right after function#2 is called, the values are changing.
This confirms the corruption. But I do not know how.
Any help is greatly appreciated to solve this problem.
Thank you very much,
Reddy
