Hey everyone,
Environment is 4.15 ACS + XCP-NG 8.2 on fiber shared storage.
I notice a strange VR behavior happening once in a while (~10
mins or so) . The virtual router is generating significant amount of usage on
the storage for about 1 min or so.
Storage usage window corelates with CPU 100% usage as well.
After some troubleshooting - the process that does the CPU load
is kswapd0. it looks like the VR is swapping memory on the storage.
An error message pops up once in a while in the cli -

The disk of the VR is not full - https://imgur.com/37JU1Dg
It has happened a few times now and usually what I do is delete
the VR and let ACS put a new instance, but that postpones the issue and does
not resolve it.
Any idea of the root cause and how to fix ?
Regards,
Jordan
