Problem IC66898
|
Status: Closed |
MEMORY LEAK IN DB2 WHEN CALLING UNFENCED CLI ROUTINES |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
A small amount of memory is leaked in the DB2 server process on
each call to a trusted/unfenced CLI routine.
This leak can build over time and may cause memory
overcommitment on a system, potentially resulting in
performance degradation and eventually memory exhaustion.
.
For example, the problem was found in this case when running a
large number of xml decomposition which
invokes this trusted/unfenced CLI routine causing the memory to
increase on the system and eventually
memory exhaustion. |
