I think you're missing some uses of these. "Servers" will never initiate a reconnect to the other endpoint, but they can go into standby and queue up new messages for if a reconnect does happen. > And "lossy" and "resetcheck" also seemed redundancy.

Not quite. The PR removes one of the resetcheck gates, but there are two of them. :) If you look at the commit which added resetcheck you'll see that it's about some peer connection races, but again lossy is used in a lot of other places orthogonal to resetcheck. -Greg -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
