> Running the tests in {{RestServerEndpointITCase}} in a loop may cause a Kernel panic on OS X. I have observed this to happen with tests that use the {{OkHttpClient}}, such as {{testDefaultVersionRouting}}.
> To run the aforementioned test in a loop, apply the git patch in the attachment, and execute the following command:
> {code}
> mvn clean integration-test -pl flink-runtime -am -Dtest=RestServerEndpointITCase -Dfast -DfailIfNoTests=false -Dsurefire.skipAfterFailureCount=1 -Dlog.dir=/path/to/log-dir -Dlog4j.configuration=file:///path/to/flink/tools/log4j-travis.properties
> {code}
> The test eventually fails with the exception below. A few moments later the operation system restarts.
