==================================================================
Reason for the issue:
When initially create the datafile with MAXSIZE specified and then resize the file > MAXSIZE and the datafile in autoextend mode then you may hit the bug.

================================================================
Permanent fix:


Apply the patch number is 8392341.

=============================================================
Workaround:
Try to resize the datafile for both undo and temp and check if this will fix the issue.

If the issue still exist disable the autoextend and this should fix the issue.
