[hylafax-users] 503 Permission denied. Cannot inherit from job 4

[FOO SOON LOKE <fsloke@xxxxxxxxx>]

 Last Friday I try to fax out some document...

Any error has encountered:
===========================================================================
An error occured while submitting the fax job phone number "960281230" ( will try to submit the fax to the other numbers anyway):

503 Permission denied; cannot inherit from job 4.
===========================================================================

I got fax using "960281230" number before. It works... But on Friday the HylaFAx encounter problem. May I know what causes the error above? Is it the previous document has to deleted after it faxed out?

Thank
