FREB: Need to add FREB tracing log when there is a failure of mixed process mode applications or multiple instance of in-process applications

I think we need to add FREB tracing log when there is a failure of mixed process mode applications or multiple instance of in-process applications. Currently, we set only event log in that error situation and users can't figure out the common issue only with Freb tracing log.
