If the HA mirroring connection resets (tmctl ha_stat, in any of the columns expires, aborts, or overflows), then any flow-close messages in the failed batch will be lost. The flows will age out normally in the standby unit.
Possibly higher memory usage on standby.
Resets in the HA mirroring channel (tmctl ha_stat, any non-zero numbers in expires, aborts, or overflows).
None. However, high resets on the mirroring connection indicate that failover is unlikely to work properly, and should be corrected first.
Sweeper now kills stale mirrored flows.
