Error description
Environment: ITM 630 FP7 Windows R2 Agentless Agent Problem Description: Executing multiple Situations for 100+ Subnodes on an Instance will abend the Agent. The corresponding R2 Agent trace log will contain the following trace statements prior to the abend when (UNIT:KRA ALL) tracing is set on the failing thread: kraaevxp.cpp,559,"AddWorkEventElement") *EV-INFO: Add event work element .... kraadspt.cpp,874,"sendDataToProxy") Entry kraadspt.cpp,895,"sendDataToProxy") Sending 0 rows for ... kraafira.cpp,695,"Sample") Entry The problem exists in the queue handling performed by the TEMA function AgentEventExporter::AddWorkEventElement. The function does not lock the queue prior to enqueuing an element. Detailed Recreation Procedure: Extremely difficult to reproduce. Configure R2 Agent to have one Instance which has 300 SubNodes Create a Situation to run for each Subnode Wait for timing conditions to arise which results in an abend of the Agent
Local fix
Reduce the number of situations and of subnodes configured.
Problem summary

The corresponding R2 Agent trace log will contain the following trace statements prior to the abend when (UNIT:KRA ALL) tracing is set on the failing thread: kraaevxp.cpp,559,"AddWorkEventElement") *EV-INFO: Add event work element .... kraadspt.cpp,874,"sendDataToProxy") Entry kraadspt.cpp,895,"sendDataToProxy") Sending 0 rows for ... kraafira.cpp,695,"Sample") Entry Agent Instances that have several hundred Subnodes reporting to them may abend due to the Agent accepting Situations, such as Service Interface requests.
Problem conclusion
Corrected the code to ignore Situations which originate from the Service Interface and are Private Situations. The fix for this APAR is contained in the following maintenance packages: | service pack | 6.3.0.7-TIV-ITM-SP0002
