I have noticed that the controller is launching multiple instances of a probe.
This has been seen with the following probes but could be seen with others not listed here:
sql_response
processes
jdbc_response
sqlserver
windows and linux robots 9.38 and prior
After upgrading the robot to 9.40 and setting "local_ip_validation = yes" in the robot.cfg this problem did not occur again in the environment where it was observed.
