RPTS1002E

RPT is unable to execute a schedule because one of the ports(%1) it uses to communicate with the agents has been taken by another RPT(or other server) process. Ensure only one RPT instance is running.

Typically, this error occurs when a server process on the workbench computer is listening on the same port that HCL OneTest Performance requires. This error can also occur when two instances of HCL OneTest Performance run on the same workbench.
Identify and stop the other process or service on the workbench that is using the ports that HCL OneTest Performance requires. Restart HCL OneTest Performance. You can also change the ports that HCL OneTest Performance uses by configuring the workbench and all agent computers. To change the ports, click Window > Preferences > Test > Server, and click Preferences > Test > Performance Test Reports > Web Reports.
