I have checked that lines also. How can it be possible to exceed this
limit? I am sending some strings, well formed strings as I have my own
debug that tells me what is happening there.

It's a little bit too hard to run it like that, because it's a plugin in
another aplication. I use my own debug.

I am tring to send SNMPv1 traps.
As I said, this plug-in used to work with a previous version of
net-snmp. Now, I have seen that the error and return codes are changed,
I have changed it to match.
I run snmptrap with -Dsess_async_send and no debug was printed. As I
constructed the plugin following the snmptrap.c file, with the
difference that I take my parameters from a file, I expect to work the
same, but it doesn't.
I will review again the code, maybe I miss something.
