I have a document library in SP2010 where a document has been checked out by "System Account" and locked as Read Only.
Logged in with site collection administrator credentials (which also have full control in the web app via policy) I am not able to edit, check in, discard checkout, administratively force check in, or delete the document. I am able to open it in read only mode in both the client and Office Web Apps. This library does have a standard, OOB approval workflow attached. The WF is not customized. I see that the Workflow Timer Job becomes set to "Paused" when this runs.
I have tried cancelling the the workflow tasks and terminating the workflow. But, it does not release the check out by System Account or the read only status.
I logged in as the Farm Admin account, which is recognized as System Account, and tried all these things, but still no results.
I have cycled the SharePoint Timer service, but this didn't alleviate either the check out status or the read only lock.
I have restarted the WFE server and the SQL server. But, the check out and lock remain.
I do not have the option of deleting this document library as there is too much content to manage. This is only a single document in the library, not all the documents in the library.
So, how do I access this lock and remove it?
