Problem IT10769
|
Status: Geschlossen |
EXECUTION OF EXTERNAL THREADSAFE ROUTINES MAY LEAD TO DB2 CRASH DUE TO MEMORY CORRUPTION. |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problembeschreibung: |
Execution of external threadsafe routines like SNAP_GET_AGENT or
SNAP_GET_APPL may cause memory corruption resulting in a DB2
trap, FODC_panic.
The following stack should be seen in the DB2 trap file
indicating termination of FMP process (function
sqlerTerminateFmp) followed by clean up of
thread resources (function sqlerCleanThreadResource).
