DB2 - Problembeschreibung

Problem IT06378 Status: Geschlossen

MEMORY LEAK IN GEO-SPATIAL CALLS WHILE ACCESSING SPECIFIC TYPE OF DATA

Produkt:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problembeschreibung:
There is a memory leak which are triggered by Geo-spatial 
function calls such as st_intersects() when run on specific 
types of data. The symptoms are shown in: 
 
a) top output ( The RES - SHR value for db2sysc would be 
unusually large ) OR 
b) ps -elf output will show an unusually large size for the 
db2sysc pid and it will slowly keep growing AND 
c) db2pd -memb pid=<db2sysc pid> will show OSSe blocks allocated 
with LOC 43 or 60 and File 0. 
 
A snippet of the output from db2pd -memb output:
