      We have not seen this issue before. In fact we have never really had a mongod crash. The only thing we do see is there was a lot of network flapping or loss at the time of this crash.

      Description

      We have a 3-node replica set. 2 nodes are in one data center (chi3 and chi4). And 1 node is in another (can1). The mongod on chi4 crashed with the below stack trace and log.
