    Details

    • Subcomponent:
      jfr
    • Resolved In Build:
      b81

        Description

        The code used to calculate various CPU usage statics depends on out-of-date interpretation of various fields in /proc/stats that no longer hold true since Linux 2.6. This can result in issues like JFR reporting 100% CPU consumption for IO heavy loads.
