An agent attempts to export historical data, the export fails and writes an error to the Agent log:
sourceObject open() failed, status = 66, for object <KPX_CPU_SUMMARY> table KPX08CPUSU appl KPX
Data missing from data warehouse and history binary files continue to grow at the Agent
Resolving the problem
Error code 66 indicates there is a problem with the configuration file (khdexp.cfg) used by the agent.
1) Stop the agent
2) Move the khdexp.cfg file to a storage location
3) Restart the agent
Once the agent restarts, it will generate a new khdexp.cfg file, and exports will begin.
