The Application Performance Analyzer Client Server subtask named: server failed to complete the START command for client at IP Address: ip-address. The reason for the failure follows in messages: CAZL077I and CAZL078I. This error should never happen, but if it does, it might indicate that the Application Performance Analyzer PDTCC extension is being probed for a possible attack. It might also indicate an incompatible version of the workstation code is attempting to communicate with this PDTCC extension.
