MEMORY LEAK IN REGEX FUNCTION
|
| Produkt: |
DB2 FOR LUW / DB2FORLUW / B10 - DB2 |
| Problembeschreibung: |
A query using a REGEXP built in function can potentially produce
a memory leak.
Using a command like this:
db2pd -db dbname -memblocks appl 20 sort | more
You might see a the total size growing for a function inside
sqlri_regexp.C like this:
Memory blocks sorted by size for appshrh pool: (PoolID: 20,
SecondID: 0, PoolAdd
r: 0x00007F0C3E3804C0)
PoolID PoolName TotalSize(Bytes) TotalCount LOC File
20 appshrh 1115552768 8536 1526
sqlri_regexp.C
20 appshrh 557776384 8536 1539
sqlri_regexp.C
20 appshrh 956032 8536 1482
sqlri_regexp.C
This can lead to an SQL0973N error where the database has run
out of application heap. |
