| Problem description: |
During SQL/XML or XQuery compilation, before DB2 9.5 FP6 or
earlier versions, a very large and complex predicate in the
query being compiled may cause the DB2 instance to abend due to
a stack overflow exception. In the stack trace, the function
sqlnr_clusterQunsFindCluster() is repeated. DB2 might also
issue SQL0973N even after AGENT_STACK_SZ has been increased to
the top range. |
