Jetty web server is automatically shutting down very frequently on EC2


Looking for help. Jetty 8.1.14.v20131031 is running on EC2 Ubuntu 12.04. It shuts down automatically in 3 hours after it is started. Just to confirm that it is not the issue of my code I removed war file from the server and started with default [spdy.war and test.war] but the same outcome. It got shut down after 3 hours. Jetty does not log any error in the log. Just to mention that this issue started a month ago, before that it was working fine.

Here is the log -

Solution

  • I started jetty ignoring the hangup signal and this work around seems to be working as of now. I started jetty with this command [nohup java -jar start.jar &]. But root cause of shut down signal is still away from my sight.
