VM on CSV goes Pause-Critical

Hi guys,

I hope some of you can enlighten some questions.

How many hosts/nodes do you recommend in a Hyper-V Cluster?

We are having som CSV issues when thay are in some cases when moved to anoter hosts are about 30 to 60 seconds and therefor the VMs on "that" CSV is going in "Pause/Critical" mode, the hosts is connected to our NetAPP AllFlash SSD via Fiber Channel.
We have looked in to the number of hosts in the Clusters (the biggest Cluster have 15 hosts, and the smallest Cluster have 4 hosts) - all hosts have the same OS installed, patchlevel and so on - som Clusters are server 2016 and others server 2019.
It looks like it is something that develops over time (1+ month) and a reboot of all of the hosts (one at the time) seems to fix the Pause/Critical issue. 

Please let me know i any of you have experiend something like.

Best and kind regards.
