DB2 INSTANCE MIGHT TRAP IN SQMAGENTRTNSTACK::GETRTNCTXFORSND() WHILE CONSTRUCTING THE ROUTINE CONTEXT INFORMATION. | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 | |
Problembeschreibung: | |
If the MON_HEAP_SZ database level configuration parameter is configured to a low value OR if the memory available in monitor heap is not sufficient, routine monitoring infrastructure may fail to allocate memory for statement nodes used for tracking the statements executed by the routine. As a result, an agent can trap inside getRtnCtxForSnd function while accessing the statement nodes.
