> I do not understand the logic here.  I always want to see the reason for the failure. Otherwise, I do not know why it is failing unless I restart the server with debug logging enabled.  By that point, the error may have cleared.  Please just use the Exception in the WARN output without adding confusing logging for debugging.  This is never an expected behavior... that enabling debug would change a _warn_ level log message.
> Also... please remove the ellipsis, they add no value.
