Hi Robert and Thomas,
<< I am still watching the movement of the process and will test the
new version for days, ..>>
I was away for few days, Today, I check the snmptrapd, it core dump less
a day (6/21 14:01:54 to 6/22 11:31), although the memory did not
increase, but it is still core dump in the same place, please see the
attachment. So I am guessing the memory leak may be not the root cause
of the core dump ??
Any help will be appreciated.
Thanks.
Lan

Hi Robert and Thomas,
I updated the code according to Robert's new patch, make and install, it
has run for almost 30 minutes now, the memory does not increase at all,
it keeps as 5256K and 3680K, it is great. I am still watching the
movement of the process and will test the new version for days, the
receiver currently process the incoming traps almost every or other
second.
I am really appreciate you guys instant support.
Thank!
Lan

Sorry, I missed a part - a handler was installed globally, not
respecting the
agentx flag. The fix is simply moving one line... Here is a patch
against a
clean 5.2.1 snmptrapd.c.
