Problem IC61458
|
Status: Geschlossen |
Memory is leaked when an EDU for unfenced store procedure terminates |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problembeschreibung: |
Small memory buffer, related to the thread control block , is
leaked when a db2 agent terminates.
The memory leak happens only for the agents, executing unfenced
store
procedures.
The leaked memory area can be reused by DB2 if OS creates new
threads with reused thread ID.
The leaked memory would be released when libdb2e.so library is
unloaded from the DB2 engine ( db2sysc process ) |
