Workflow Hangs With Status Reason: Waiting for Resources... Organization Status : Failed - Resolved

I had a problem and solved it :

all of my workflows hanf with status reason : Waitin For Resources

and Import Data didn't work.

I check my Organization in Deployment Manager and saw this: Status: failed

So I get a back up from my database and Delete Organization

Then Import Organization and use my back up

So : Status: Enabled

P.S:

you can cancel all of your jobs in Database with this query:

UPDATE AsyncOperationBase SET StateCode = 3 -- Completed
, StatusCode = 32 -- Canceled
, [Message] = 'WorkflowErrorPatched'
WHERE StatusCode = 20 -- In Progress
OR StatusCode = 0 -- Waiting For Resources
