             Summary: Concurrent repeated add attempts create orphaned blocks
                 Key: TEIID-5390
                 URL: https://issues.jboss.org/browse/TEIID-5390
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
            Priority: Critical
             Fix For: 11.0, 10.3.2, 10.2.3


If both a user thread and the buffer cleaner are evicting the same batch/page at the same time - and multiple attempts are made by one of the threads it will result in duplicate inode / data block entries being created, which then cannot be cleaned.
