MEMORY LEAK IN DB2SYSC PRIVATE MEMORY WHEN AN EXTERNAL CONVERSION TABLE IS USED |
| product: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problem description: |
Description:
The db2sysc private memory may be leaked when following
conditions are met:
- External conversion tables are used (*.cnv exists in
sqllib/conv/ directory)
- The database code page and the application code page are
different
- Trusted routines are used
This memory leak cannot be observed by db2pd -dbptnmem or
MON_GET_MEMORY_SET/POOL, but ps or other OS monitoring
tools(e.g. svmon in AIX) report the increase of the private
memory. The db2pd -memblock pid=db2sysc_pid will show the many
blocks from OSSe LOC=239.
For example:
Memory blocks sorted by size:
PoolID PoolName TotalSize(Bytes) TotalCount LOC File
OSSe OSSe 167033120 3941 239 0
0 13222440 105 176
1235720678
0 5242880 40 8429
