Status: Closed |
ST_BUFFER SPATIAL FUNCTION CRASHED DB2 WITH MEMORY CORRUPTION FAILURE |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
Due to data-specific conditions which have not yet been
identified, the ST_Buffer spatial function very occasionally
results in memory corruption which can cause the DB2 instance to
hang or crash. The db2diag.log file shows a stack trace similar
to the following:
