Status: Closed |
Small memory leak in database heap in pureScale environment when performing DDL or bufferpool/tablespace monitoring |
| product: |
DB2 FOR LUW / DB2FORLUW / 980 - DB2 |
| Problem description: |
In a pureScale environment, a small amount of memory is leaked
in the database heap when performing DDL and potentially during
tablespace/bufferpool monitoring.
Symptoms are typical of a slow memory leak. Eventually system
memory may become overcommitted causing paging and performance
degradation.
"db2pd -db <db> -memb 2"
will show growing memory allocations as follows (note high
TotalCount):
Memory blocks sorted by size for dbh pool:
PoolID PoolName TotalSize(Bytes) TotalCount LOC File
