> WARN level "WALs outstanding" from CleanerChore should be DEBUG and are not always correct.
> I left a cluster configured for ITBLL (retaining all WALs for post hoc analysis) and in the morning found the master log full of "WALs outstanding" warnings from CleanerChore.
> Should this really be a warning?

> {quote}
> If someone has configured really long WAL retention then having WALs in oldWALs will be normal.
> Also, it seems the warning is sometimes incorrect.

> {quote}
> There are no WALs under archive/.
> Even at DEBUG level, if it is not correct, then it can lead an operator to be concerned about nothing, so better to just remove it.
