Executing test cases by TestExecute triggering via Jenkins

Hello All,

I am running Test Execute service in one of the Jenkins node, from Jenkins Master where I have created a Job which will trigger the Test Execute to execute certain test suite on Jenkins node (where the Test Execute is running as a service) but I am seeing below errors and Job is getting exited (please find attachment screen shot for more info.);

[Test Complete] Test runner exit code: 1000.
[Test Complete] [WARNING] Error: Test Execute 14 is already running..

 Kindly help me to fix this problem.

Thanks in advance
