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.
