      Hello,

        Mongod thread hangs on "recvmsg" system call because of this seeing very high load on replica set. I don't see any COLLSCAN in logs. When thread hangs read and write queue increases which is obvious. Not sure what is happening with this replicaset.

      Currently running 3.6.16 mongod on aws i3.16xlarge instance type. PRIMARY is failing over all the time whenever all the threads hangs.
