| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
db2pd -memblock output for db2acd shows small memory leaks for
db2acd.
Autobackup evaluations happens every two hour interval. And
after each evaluations, db2pd detects a leak of 3 allocations
from LOC 56, and 1 allocation from LOC 410 for file 521867987.
A single evaluation leaks:
3 allocations from LOC 56 ; and 1 allocation from LOC 410.
After one evaluation (2hours):
Memory blocks sorted by size:
PoolID PoolName TotalSize(Bytes) TotalCount LOC File
88 private 112 3 56
521867987
88 private 11 1 410
521867987
After two evaluations (4hours):
Memory blocks sorted by size:
PoolID PoolName TotalSize(Bytes) TotalCount LOC File
88 private 224 6 56
521867987
88 private 22 2 410
521867987
The problem happens only for autobackup evaluations. It does not
happen for the other plugins like autoreorg or autorunstats even
though it uses the same parser code. |
