Problem IC72468 Status: Geschlossen

MEMORY LEAK IN APPLICATION HEAP DURING REBIND

Produkt:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problembeschreibung:
Memory leak in application heap happens during rebind 
 
The leak can occur on any rebind that specifies an option such 
as RESOLVE, REOPT or VERSION 
 
Note that a rebind can come from the REBIND command, db2rbind 
(which by 
default specifies RESOLVE CONSERVATIVE) or by calling the 
SYSPROC.rebind_routine_package() routine
