I have never noticed this. However, due to the other issues the board doesn't see much network traffic. I would suggest checking bandwidth utilization and pinging between the modules. They only have 100Mbit interfaces and saturation causes packet loss.

[linux-image-next-sunxi64_5.99_arm64.deb]I recently moved to linux-image-current-sunxi64_5.3.9 and the time jumps have ceased. However, now the Ethernet device will shut off.

You could try adding some fans to the case and heatsinks to cool chips. Additional, cooling and an ATX power supply are on my todo list. The clusterboard chips show around 90F when ambient is around 60F.
Does any one have a solid idea on what the problem could be?
