           Summary: IDB transactions never reset if the Web Process ends
                    before cleaning up
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2
         Component: WebKit2
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jpfau at apple.com


With the Database Process enabled, IDB transactions are almost entirely managed by the Web Process, even though the backing store is handled by the Database Process. In the event that the Web Process ends before it cleans up an IDB transaction, either due to a bookkeeping error, or by crashing, the Database Process will never clean up the transactions that were being managed by the Web Process. This leads to memory leaks at best, or the Database Process getting wedged at worst.
