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

Typically, this error occurs when a server process on the workbench computer is listening on the same port that Test Performance requires. This error can also occur when two instances of Test Performance run on the same workbench.
Identify and stop the other process or service on the workbench that is using the ports that Test Performance requires. Restart Test Performance. You can also change the ports that Test 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.
