> This issue is about adding a lock picker to the HbckService
> Over the w/e I had interesting case where an enable failed -- a subprocedure
> ran into an exclusive lock (I think) -- and then the parent enabletabled
> tried rollback. The rollback threw CODE-BUG because some subprocedures were
> in unrollbackable states.... so we ended up skipping out of the enable table
> procedure. The enable table procedure was marked ROLLBACKED... so it got
> GC'd. But the exclusive lock it had on the table stayed in place.
> The above has to be fixed but for the future, we need way to kill locks
> otherwise only alternative if removing master proc wal files -- which is a
> bigger pain restoring good state.
