Fastload Utility Locks due to abort- .FILLER command- possible solution?

While using utilities like Multiload, when any job ends abnormally, Teradata still holds locks and we get error 'Table is being mLoaded'.
While in case of FastLoad/TPT end, we get error 'Table is being loaded'. Even after dropping error/log/work tables, we still get same error. What I do now is just drop these tables, and recreate them.
Possible solution(read on forum) is to run same process again with empty file. So utility puts lock, and releases after successful completion.
 
Instead of that, can we use .FILLER command in fastload script so process will run without empty file, but with all empty columns and will release lock later once finished successfully?FILLER will exclude columns from loading and it should release locks.
