Looks like you are currently rebuilding parity but aren't rebuilding parity2. Why?

I thought it would be wise to reduce the load. Therefore I go step by step. Parity 1 is now finished and back online. Paritiy 2 will be finished soon. I think, those disk errors happen when there is high data transfer load on the device, e.g. from a large backup or when a VM pulls large backups. Just a feeling!

Do the drives have anything in common that might have caused them both to lose connection? Power cable? Controller?

The disks are connected to different power supply lanes but are connected to the same SAS controller, which is a LSI 9207-8i. I only have this controller, beside of the connectors on the motherboard. The LSI controller is equipped with a fan.
