#rb Juan.Legaz #jira UE-222213 #rnx - At the moment most projects allow submits with failed virtualization attempts to continue uninterrupted but that means we rely on users reporting issues to us. By raising an ensure we will get a report sent to our crash reporting systems which we can use to dig into the problems. This system will be opt in via the cmdline arg. - The cmdline arg will be passed onto any spawned child processes so that they will report too. -- Note that we also now pass '-fastexit' onto the child processes which was not done before. - We only raise an ensure if the problem occurred in the current process, it is expected that child processes will raise their own. -- We use a new enum EProcessResult to pass this info around. - The log filtering has been extended to filter out warning/error messages normally logged when an ensure fires as these will concern the end users, we don't want the reporting to not interrupt their day to day work either.
