Problem IC85694
|
Status: Closed |
POSSIBLE UTILHEAP MEMORY LEAK DURING AUTOMATIC STATISTICS COLLECTION FOR TABLES THAT HAVE A STATISTICS PROFILE |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
When the following conditions exist:
- automatic statistics collection is enabled
- a table has a statistics profile which does not include
distribution statistics for any column in the table
- automatic statistics collection collects statistics for the
table
a leak to utility heap might occur depending on how the
statistics collection was performed. The factors that can
influence whether the leak will occur are not deterministic.
The -memblocks option of db2pd can be used to look for leaks.
The leaked memory is released when the database is deactivated. |
