Hello Noel,
I have enabled logging and I'm getting this when the thread stops
processing traps. Traps are reeceived, but there seems to be a problem with
messeges being received in the time window. I don't know what could the
diference be between using the tool as provided when downloaded or with what
I'm tyingo to do. Why is the message not being in the time window? Could it
be that it takes time to process, and if so, how can I solve it?
I also tryied the latest version with the thread only receiving 4 traps.
This is what I get:
