VARIOUS MEMORY LEAKS IN DB2SYSC WHEN USING TEXTSEARCH
|
| product: |
DB2 FOR LUW / DB2FORLUW / B10 - DB2 |
| Problem description: |
Using TextSearch can lead to various memory leaks in db2sysc.
The following stack traces
for blocks that are leaking will depend on what commands are
run, select, update via
stored procedure, etc... Block sizes are omitted from the list
below because most likely
they would change based on the platform.
