Patch Set 1: Code-Review-1

Patchset:

PS1: I think it would be very interesting to understand how this phenomenon happens on your system.

a 5 second round-trip time between sending a RESET from TTCN3 until receiving the ACK from the IUT (BSC) is way too long already. 10s is just ridiculous, IMHO.

So either * TTCN3 thinks it has sent the message, but it takes a long time until it actually hits the wire, * your network has some kind of enormous delay, or * the RESET arrives in time, but something prevents the BSC from receiving/processing the RESET * or any of the above in the reverse direction for the ACK

We may very well have a bug, if we have a RTT > 5s in test execution. Merging this patch might just plaster over it.

correlating logs with pcap file should hopefully give you an idea of where the majority of the time was spent/wasted.
