| Description |
|
Shard server replica set nodes in binary version 4.4 start up in FCV 4.2 by default. If they are downgraded to a v4.2 binary, the node will crash when trying parse the config 'term' field on startup. We should not write the config 'term' field when these nodes start up in FCV 4.2. |
