Deleting Tasks in Satellite 6.1

I'm setting up a new Satellite 6.1 server and in my enthusiasm I started a bunch of repo resync tasks for RH 5, 6, and 7. Bad idea as it was taking forever to retrieve the information. Since I have a load of ISOs already, I cancelled the tasks and planned on following the install docs to simply move the rpms from the ISOs into the appropriate directories and then let Satellite sync a much smaller number of rpms. Unfortunately something got stuck and I have two tasks that have errored out waiting on the completion of two other tasks so the locks can be removed.

Problem:

Task 1 is waiting on Task 2 to complete to release the lock. Task 2 has been canceled but didn't delete the lock. So Task 1 can't be restarted.

Task 3 is waiting on Task 4 to complete to release the lock. But Task 4 has completed successfully.

Is there a way to remove tasks from the system? I'd like to clean up the canceled ones, just delete them, and delete the others and then when I get the rpms in place, simply start up new tasks to sync them.

I can certainly blow the system away and start over as this is a new install but I'm concerned that 6 months from now, for example, if I get a task stuck I won't be able to blow the system away.

Thanks for any help.
