Lately, my local development Ignition is crashing when I'm using the remote JVM debugger and running through breakpoints. Is there some kind of new "Pause the World" watcher that restarts the JVM or something?
If you have your debugger set to suspend all threads instead of the current thread then I suppose the service wrapper could think the JVM timed out and restart it if you were paused long enough... not sure though.
Try one of these in ignition.conf:
wrapper.ping.timeout.action=NONE
wrapper.ping.timeout.action=DEBUG
Also make sure that your debugger and the gateway are using the exact same JVM version. You may have to install a platform JDK and set the gateway to use it instead of the bundled JRE.
