Problem IT19457
|
Status: Closed |
INSTANCE CRASH DUE TO STACK OVERFLOW DURING EXECUTION OF AN XQUERY WITH A LARGE NUMBER OF PREDICATES. |
| product: |
DB2 FOR LUW / DB2FORLUW / B10 - DB2 |
| Problem description: |
During SQL compilation, an xquery with a large number of
predicates being compiled may cause the DB2 instance to crash
due to a stack overflow exception. DB2 should ideally cause the
DB2 agent to return an sqlcode SQL0973N upon detecting such a
scenario.
The stack trace from such an abend will look like:
sqlngStructurePool::getStructure
sqlng_xpath_node_fun::translateXPS
sqlngProcessXPred
sqlng_xpath_node_fun::translateXPS
sqlngProcessXPred
...
* The function sqlng_xpath_node_fun::translateXPS() and
sqlngProcessXPred() are called repeatedly |
