We came across the attached error while testing application built using PS 2022 R3. The QA person waited for 10 mins and this error didn't come up again. When does this error occur and is there a configuration that needs to be set so it does not exceed the number of session. We have only 1 user testing the application so surprised to see this error.
Yes, you can either ...
1) Review the PS Log file // OR
2) Use the PS API list ( http://<YourHost/IP><Port>/PowerServer/index.html. Then look for the Session API's to run. // OR
3) Use a PS Console:App - FYI: http://chrispollach.blogspot.com/2024/06/console.html

Another thing you should look is to see if the license code is being used in more than one deployment. Because if the developer may be using the same license code as the QA person for example then it is more than 1 user.
