Problem IC66999
|
Status: Closed |
MEMORY LEAK IN MON_GET_LOCKS, MON_GET_APPL_LOCKWAIT TABLE FUNCTIONS and MON_LOCKWAITS admin view |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
A memory leak of 6496 bytes per lock occurs as a result of
calling the MON_GET_LOCKS or MON_GET_APPL_LOCKWAIT
table functions or querying the MON_LOCKWAITS admin view.
The leak is from the private memory heap.
'db2mtrk -p -v' will show the leak
Before calling MON_GET_LOCKS:
Memory for agent 16
Other Memory is of size 20250624 bytes
Total: 20250624 bytes
After calling MON_GET_LOCKS to return info on 1006 locks:
Memory for agent 16
Other Memory is of size 26869760 bytes
Total: 26869760 bytes |
