                 Key: DERBY-3727
                 URL: https://issues.apache.org/jira/browse/DERBY-3727
             Project: Derby
          Issue Type: Improvement
          Components: Store
    Affects Versions: 10.4.1.3
            Reporter: Mike Matrigali


Improve the text associated with ERROR XSDB3: Container information cannot 
change once written: was 103, now 80.  It would be nice to know which
database and container at least, and possibly any other info that may have 
changed.  Maybe page/hex dumps to track down overlapping I/O errors on page 0.

Here is a stack trace reported as part of DERBY-3607, as encountered by a back
