The first time a BVC Reset times out we wait a couple seconds, but after sending the second BVC Reset all other Resets are sent directly after another without waiting.

I guess we can reject this issue since it's related to the SNS fixes you pushed?
Looking at the trace again I can't see any issue/multiple BVC-RESETs being sent. The BVC-RESET is rejected by the gbproxy with a STATUS (because sns was broken in this version). TTCN3 simply ignores that and continues resetting the ptp-bvcs which are also (rightly this time) rejected.
If you disagree please reopen.
