In the family of cgroup test there is "TestCgroupMetrics.java" which fail with some probability here and then.
The failures are more frequent on older JVMs (e.g. 8) where G1 is not a default GC yet. But the failure can be easily reproduced with G1 as well.
*How to reproduce*
Run TestCgroupMetrics.java, but modify it a bit. In method testAll() of class MetricsTestser, run "tester.testMemoryUsage();" in a loop:
```
- tester.testMemoryUsage();
+ for (int i = 0; i < 1000; i++)
+ {
+ tester.testMemoryUsage();
+ }
```
