This was seen on Sandbox on a code which is already merged to stable/carbon.
The title says possibly, as from the two similar test cases, only one has failed , it was the one where the listener was on the same member as the shard leader, which has been moved by calling remove-prefix-shard-replica.
In huge karaf.log  with some debugs look between removal starting at 19:23:10,608 and suite adding replica back at 19:23:41,773.
