      Previously running on version 4.4.8 in a three node repl set and experienced DuplicateKey bug which crashed mongodb and required resync on secondary node.

      Issue tracked here: https://jira.mongodb.org/browse/WT-7984

       

      Upgraded all nodes to version 4.4.9 which was supposed to resolve this, however, just hit the same bug again.
