      sometimes mongos failed to connect to shard servers ,like this 

      [NetworkInterfaceASIO-TaskExecutorPool-0-0] Failed to connect to 172.*.*.*:10000 - ExceededTimeLimit: Operation timed out, request was RemoteCommand 2032618 -- target:172.*.*.*:10000 db:admin cmd:{ isMaster: 1 }

[conn64648] Invariant failure event.isValid() src/mongo/executor/thread_pool_task_executor.cpp 256

      restart the mongos can solve this problem,In a few days，this problem once again.

      Now it is running normally，the mongos connet to shard servers every 15 seconds,behavior like this happen much too often. what wrong with it?
