[AGENT++] Segmentation fault while finalizing request answer!

[Carlos Vicente]

Hi again Frank,

Problem solved... I was loosing the RequestList reference somewhere in
the agent code 8(.
I'm now dealing with some manager timeouts. But I'll have to dig in a
little longer in the manager to see what I'm missing. I've already
checked out with Ethereal, and the UDP answer gets to the manager
machine. So, I'm must be doing something wrong on the Manager side.

Thanks for the help anyway :-)

Carlos

Hi Carlos,

Most likely you hit a FAQ. When you get a seg. fault
and you changed some compiler settings before
(e.g. disabled _THREADS or SNMPv3) then in 99%
of all cases you have not made a clean compilation
of *all* your libraries.

Best regards,
Frank
