Flushing and writing to Socket using javasdk

Hi

I'm using the javasdk to create a Socket connection to a splunk index for posting events in a long running process.

The socket connection is kept open for the time the process is running, but I'm not able to see any events using the dashboard before the process is terminated, and the socket connection thereby is closed. I have set tcp_nodelay to true, and flush after each write, but it doesn't seem to make any difference.

Is there any way to overcome this limitation without closing the socket after each write ?
