Hi, we are using elasticsearch 0.18,it was working fine, but recently I am facing unknown error 56 again and again, on finding its details, this error is for "Failure with receiving network data." and it is solved when whole es is reinstalled but appears again soon, Can you please help to identify and solve the problem. Thanks ---

It sounds like this failure relates to the client library you use to talk to elasticsearch, which I am not familiar with... . The fact that restarting elasticsearch "solves" it is strange, possibly it ends up forcing to close the connection from teh client, and then causing it to repoen it? So maybe this failure causes the client to to properly handle its connection?
