Hello, Kern! Thank you for explanation.

It is a bit strange - at the moment of error bacula "knows" what job
is being running but the only warning is in log-file.
Of course log file can be periodically parsed, but why not to mark job
with warning flag as at this point we can not be sure is job valid or not.
