Agent hang there without response.

The agent is hanging there without receiving responses from server. Once restart the agent, it works again. In this case, it is not an issue at the server side.

• Add some logging to your code and also set exceptionHandler on HttpClientRequest and HttpClientResponse to see eventual errors.
• Make sure the file handles are correctly closed after each iteration
• If the number of files is large, have you checked that the number of maximum open file descriptors on the client side is set to a sufficiently high number (i.e. ulimit -n)
