ArgumentError when max_message_size is nil and a message is deserialized

    • Type: Icon: Bug Bug

      We upgraded a cluster to 3.0.8 today and under heavy load the mongoS CPU skyrocketed, which caused a bunch of failures for us. Until we got the mongoS under control, we had thousands of failures from processes which seemed to be talking to that mongoS. I've attached a stack trace.

      What are your thoughts here? I've considered doing something like raising an OperationFailure with a magic reconnect string like "query failed" if the deserialize_header method ends up returning an empty array, which should rescan and reconnect.
