Dear all, just wanted to add that we will be adding the option to disable the OSHI statics gathering by the end of the week (they will be disabled by default), this will allow us to:
- Unblock the situation, once the issue is clearly identified we may think about a fix for the environments where the high CU usage is identified. - Disable and enable OSHI at runtime.
