DB2 FOR LUW / DB2FORLUW / A50 - DB2

In a rare timing scenario, it is possible for the db2stmm edu to 
cause an instance abend. 
The condition is that a scalar aggregate operation is in the 
progress of cleaning up and it used exactly 32 sort heap pages. 
At the same time, the db2stmm edu needs to be active and 
evaluating sortheap usage by scalar aggregate operators. 
 
As the db2stmm only runs every 180 seconds and the db2 agent 
running the aggregate operation needs to be exactly at the 
cleanup point, this is a very rare scenario. 
 
The db2stmm call stack will look like : 
 
 
stmmGetScalagTime 
stmmCalculateTimeSavedByScalag 
stmmGetTimeSavedFromActiveOperators 
stmmReportBenefitFromSHeapThres 
stmmGetSHeapThresSharedBenefitData 
stmmGetBenefitData 
stmmMemoryTunerMain 
stmmMemoryTunerGlobalStartHandling 
sqleIndCoordProcessRequest 
sqeAgent::RunEDU 
 
( stmmGetScalagTime may or may not show depending on the 
operating system )
