Occasional errors when .post()'ing alert to an HTTP server

In a percentage of times (5-40%), we get a Connection reset error on the HTTP server that receives the POST request from the alert node. We handle the alert just fine so this is not critical, but it seems that the connection is closed before it gets a chance to reply.

CAUSE: java.net.SocketException: Connection reset

The exception is thrown when attempting to write a response to the socket. The response is usually sent within 1ms of receiving the POST request. Is there some configurable timeout or intentional reason why we'd reset the connection so soon?

The issue names no repository files or tests. Start by reproducing the alert node's HTTP POST against a server that reports the connection reset, then trace the request and response handling; done means identifying the cause of the premature reset and confirming a reliable response or documented configuration.
