> Affects Versions: 1.6.1, 1.7.0
> Environment: *Rev:* 3566bb8987872b29aa88b8f7d5b0f122e74bd518
> *OS:* macOS High Sierra 10.13.6 (17G65)

> *Java:*
> openjdk version "1.8.0_181"
> OpenJDK Runtime Environment (Zulu 8.31.0.1-macosx) (build 1.8.0_181-b02)
> OpenJDK 64-Bit Server VM (Zulu 8.31.0.1-macosx) (build 25.181-b02, mixed mode)
> Reporter: Gary Yao
> Priority: Major
> Fix For: 1.8.0

>
> 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.
