I use mongodb(v2.0.1) in sharded environments.

10 threads insert to the Mongos

The command in shell to start the mongos is below:
./mongos --port 35000 --configdb "218.241.106.161:28002" --chunkSize 1024

Every few minutes,the mongos log print these message:errmsg: "chunk boundaries are outdated (likely a split occurred)", ok: 0.0

Is anyone tell me how to fill this problem?

thanks.
