Hi,

Where did you get the logs? Is this from mongos? Which version are you using?

Did this resolve eventually or do you always get this error?

Thanks!

Hi, 

Did you fix this? If so, can you please tell me how? 

I have the same error message in my mongos log with version 2.2.1. At 04:22 my mongod instance is closed somehow and there is nothing in the mongod.log.
