DB2 - Problem description

Problem IT19151 Status: Closed

CALLING DBMS_SQL ROUTINES CAN LEAK MEMORY BLOCKS.

product:
DB2 FOR LUW / DB2FORLUW / A50 - DB2
Problem description:
The condition to hit this issue, is to have the same DBMS_SQL 
call (like: open, fetch, ...) being called more than once. Once 
the problem happens, we can observe symptoms in output of the 
commands: 
 
DB2_PID=$(db2pd -edu | grep "db2sysc PID" | awk '{print $3}') 
 
db2pd -memblocks pid=$DB2_PID > memblock 
 
In case occurrence of this issue, in the output we will see many 
memory locations with following signature: 
 
Address            DataAddress        PoolID     PoolName 
BlkAge Size(Bytes)  I LOC   File 
0x0000000110390068 0x0000000110390080 0                       1 
504          1 150   2878669185 
 
Please note that line number (LOC) might change between 
fixpacks/releases, however we should still report extensive 
usage on the file 2878669185 itself.
