The way you are using this looks correct.

The startup process would not/should not fail in this way and there
should be additional messages between the log entries from 23:03 to
23:07. I don't see any reason for a 4 minute wait at that point,
especially since previous files took 5 seconds. Are you showing us the
whole log?

Please re-run this at DEBUG3 so we can see what else is happening.
