BugId 4660521

Problem Summary: When an HTTP server is killed on a node, it leaves a PID file on that node. Next time the HTTP server is started, it checks if the PID file exists and checks if any process with the PID is already running (kill -0). Since PIDs are recycled, there could be some other process with the same PID as the last HTTP server PID. This will cause the HTTP server startup to fail.

Workaround: If the HTTP server fails to start with an error like the following, manually remove the PID file for the HTTP server to restart correctly.
