Try closing the channel if java.lang.Error prevents sending error responses to the client ----------------------------------------------------------------------------------------- Key: WFCORE-1220 URL: https://issues.jboss.org/browse/WFCORE-1220 Project: WildFly Core Issue Type: Sub-task Components: Domain Management Reporter: Brian Stansberry Assignee: Brian Stansberry Fix For: 3.0.0.Alpha4 Beyond the basic work on WFCORE-1134, look into further reaction when Errors occur and the server or HC cannot even send an error response to the caller. If we get to this point, the task has already failed to handle a problem and now we can't notify the remote side either. Most likely this is an OOME situation, although any Error here means a major issue. Options: 1) Try and close the channel to disconnect this process from the remote end so it doesn't disrupt the remote end. If this is an intra-HC or HC-server connection a successful close will remove this process from normal domain control. If this is a server the HC still has some control over the server via the ProcessController, e.g. to handle a 'kill' or 'destroy' management op. If this is a slave HC, the slave is disconnected from the domain. Either a server or a slave HC may try to reconnect, although it's likely better if that fails and the user just restarts the process. If the remote side is an end user client (e.g. CLI) then a successful close will be noticed by the client. The user can reconnect or take action to terminate this process. 2) Commit suicide via SystemExiter.exit. But I'm not certain complete termination of the process is how we want to deal with problems with management requests. Probably some sort of configurable policy would be better.
