Fixes #3415
@ahmetmircik Yeah I could reproduce the issue by running all other tests in parallel so system is under more heavy load. I I changed "Thread.sleep(2000)" to "Thread.sleep(4500)" to make total passed time more closer to TTL.(From 5000 + 2000 = 7000 to 5000 + 4500 = 9500). And yes I have run the test on master
