Hi team,

We have installed perfsonar-toolkit in an Ubuntu 20 (vmware image) and we have persistent high CPU issues due to java process (user logstash) even when no perfsonar test are running.

We have reproduced the issue in 2 different Ubuntu 20, rebooting of the system doesn't fix the issue, as soon as the vm is up CPU keeps high.
