Comment 12 for bug 1803964

We haven't had a single occurrence of the issue since early this week, see [1]. We had several changes in the meantime:

- RDO Cloud update and hypervisor reboot
- Nodepool restarts due to an internal error

Those changes might have contributed to this, so we could close the issue for now, and reopen if we see new instances of it.
