Thank you for reaching us out.
The Job storage location is a default one and could not be modified. Although the log file points to that location it may be different based on the setup you have. What other locations may be occupied you could read in this article
Anyways, the reason for the tests to not run isn't actually that message you have noticed - it is more as a result of a stuck job that hadn't finished and therefore prevent the setup to work as expected. To fix that you could perform the following steps:
1. Open the Results tab in Test Studio and then Manage Results
window. Delete any entries which do not have end time (if applicable).
2. Exit Test Studio and the Test Runner on any machines in your setup.
3. Open Services on the machine which host the Scheduling server and restart the Telerik services
4. Start Test Studio and the Test Runners, connect the project to the Scheduling service and try to run a sample test list.
Additionally I would like to inform you that with our latest release 2018.1 we had implemented a test list property
to prevent such unfinished jobs to stuck - this is the RunnerResponceTimeout
and it will terminate the execution if there is no response for the set amount of time.
I hope this information will be helpful to you. Though in case of further questions please let me know! Thanks!
