Aside from having those, everything appears to be working as normal. Failing over between servers works OK (VIP is moved).
No further errors are shown, not even when in DEBUG level
Versions of the related components and OS (frontend, hypervisors, VMs):
Opennebula 5.4.5
Steps to reproduce:
Just wait for the errors to randomly appear
