| product: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problem description: |
The conditions for this to happen are:
- The table must contain at least one LOB column.
- The table must be partitioned in DPF system.
The memory corruption can create all sorts of traps but here are
some found
for this case:
0x00007F865C0DFB60 SQLO_MEM_POOL::MemTreePut + 0x0260
0x00007F865C0DB845 sqlofmblkEx + 0x0225

0x00007FF1F7ED5273 sqleMappingFnServer + 0x04c3
The corrupted memory would show the following pattern:
