| Description |
|
We have a tag-aware sharded cluster with each node being a 3 member replicaset of which 1 member is hidden. In this particular instance, the hidden member keeps switching the sync source between Primary & the other Secondary and rolls back updates after every switch. After a couple of such switches and rollbacks, it enters into an invalid/inconsistent state and crashes. Attached is the log file for the mongod instance showing this. |

Log files from primary & secondary mongod from the same time we see the issue in the hidden secondary. |
