             Summary: Bypassing Ghost Packages in SCD
                 Key: SLING-7620
                 URL: https://issues.apache.org/jira/browse/SLING-7620
             Project: Sling
          Issue Type: Bug
          Components: Content Distribution
    Affects Versions: Content Distribution Core 0.2.8
            Reporter: Ankit Aggarwal


Sometimes the distribution package gets deleted from the queue [0] but the actual item in the distribution queue [1] is not deleted leading it become a Ghost Package. Because of this same item is picked up again and again resulting in queue blocking and repeated warnings:

We need to make the code fail safe to handle such situations i.e. deleting the item in the distribution queue if it is not able to find the corresponding package.
