Status: Closed |
INSTANCE CRASH USING WEB SERVICES WRAPPER
|
| product: |
DB2 FOR LUW / DB2FORLUW / B10 - DB2 |
| Problem description: |
When a query is executed against a web service wrapper the
instance will crash.
Example stack:

The real crash point is not inside the method
XML_ODH_Query_Execution, instead it is inside method
XML_ODH_Xalan_Interface. This relates to memory management.
While allocating memory through the new operator, the default
compiler allocates memory at high address and while referencing
this memory, the instance crashes. |
