There are bugfixes in 1.8.1, one solves a repeated state machine
activation and that could be what you are seeing too, once in a while.
And for the second one, I think this may be a TCP Fastopen failure and
it gets printed like this instead of ignored.  What I have done is
squelch that message for high verbose debug output only.  That one is
now committed in the repository for future release.  Thanks for the report.

Best regards, Wouter
