You may encounter this problem when the following sequence of
events occurs against a column organized table:
1. Updates or deletes that empty at least a full extent in the
table
2. Reorganization of the table using the RECLAIM EXTENTS option
(this is automatically done for column organized tables when
DB2_WORKLOAD=ANALYTICS is set and the database config parameters
auto_maint and auto_table_maint are set to ON)
3. A statement on the affected table that attempts to scan a
portion of the table that has been reclaimed
