I seem to get both, or they are related and/or one and the same.
That is, I get the:
2011-08-05 09:13:56.861 Protocol version check failure.
The response to MYTH_PROTO_VERSION was empty.
This happens when the backend is too busy to
respond,
or has deadlocked in due to bugs or hardware
failure.
errors on my backend when a frontend tries to connect after the backend
has begun recording(s).

But I also see those DB threads in my stack traces.
