Subscriptions not completing. Processing: 0 process of 2 total; 0 errors

Question

We have subscriptions that have run for many months, all of a sudden radomly, some of the subscriptions say 'Processign: 0 processed of 2 total; 0 errors.  When looking at the ExecutionLog3, it shows that the reports are in Render as the ActionItem
and the status is 'RsAccessDenied'.  Now this doesn't make sense since other subscriptions are using the shared datasource and they are running just fine.   If anyone has any suggestions as to why this is happening or what we can do to stop
it from happening that would be appreciated.  We have found that deleting and re-creating the subscription then works.   Remember this is random with the subscriptions, so it is hard to narrow down why it's happening.

Hi Renee_C,
When a scheduled operation is defined, the report server creates a corresponding job in SQL Server Agent and runs the job on the date and time specified in the schedule.
According to the status "0 processed of 2 total; 0 errors", the problem can be caused by the event processing threads are all tied and not processing the events as fast as they arrive, so you will miss some of them.
Please check to see if you can find record in these two tables: ReportServer.dbo.Notifications; ReportServer.dbo.Event.
Please check information one by one to find the root cause:
Check two tables below in the reportServer DB: ReportServer.dbo.Notifications; ReportServer.dbo.Event.
If these table have information, take reference as below:
This main issue is the event processing threads are all tied and not processing the events as fast as they arrive. If you have a lot of subscriptions, if several instances of the event were running at the same time occupying all of the threads or when a lot
of subscriptions are set to fire at the same time, and they may take a long time to complete, so the subscription processing cannot keep up and falls behind. In this case, you may encouraged to run them at different times if possible.
You can check the detailed error log (default location: %programfiles%\Microsoft SQL Server\<SQL Server Instance>\Reporting Services\LogFiles),
Please check the log and if you find more details error message, please provide us to move more quickly toward a solution.
