Created attachment 1249053 [details] storage node screenshot Description of problem: See attached storageNode.png, the exception is very probably thrown because the Heap Used metric has NaN value because it's not enabled by default. Version-Release number of selected component (if applicable): JON3.3.8 How reproducible: Always Steps to Reproduce: 1. install JON 3.3.8 2. navigate to Administration->Storage Nodes->Your storage node 3. Heap Used metric should be NaN because it's not enabled by default Actual results: globally uncaught exception Expected results: No exception because of NaN Additional info: See bz1138328, they didn't find a root cause but it very probably the NaN values.
I've already reproduced this issue disabling the Heap usage metric manually, also I sent a PR for fix this.
