RN528 Bond interface bond0 has slave interface eth0 offline

How to diagnose this???
Have you downloaded the log zip file, and looked in there? network_settings.log has the packet statistics - I'd expect to see errors in system.log and kernel.log when the problem occurs. Perhaps look at the network stats on the switch.
As a test you could try breaking the bond, and just using eth0. Then see if the interface works reliably that way.
FWIW, I'd be surprised if bonding gives you a performance boost when you are already running 10GBaseT. Are you using SSDs?

Latest is actually 6.10.3, but I don't know of any bug fixes for bonding in that release. https://kb.netgear.com/000061727/ReadyNAS-OS-6-Software-Version-6-10-3
Thanks, I looked at the “logs” tab (not a zip file though??), doesn’t say anything useful. I’m not sure where to fetch that zip file from. With dual ETH on both PC and NAS the speed is closer to 2 Gbps than 1 Gbps so there is some benefit. Also, as noted this has been Rick solid for a year now. Nothing has been physically moved, just OS upgrades as they come along. Sorry, yes Both NAS’s are on 6.10.3. I can tear down the bonding but it was some learning/work to get it configured and stable, hate to go through that again. Frustrating.

Speeds quoted are gigabits/sec of course. Monitoring speeds with simple Windows File Explorer transfers.
Offline issue has been resolved, turned out to be a serious Orbi 11ax bug that has just been patched. Devices have remained fully online for over a week now since the patch.
Thanks for the assistance with log files too, good for future reference.

Then you are getting two gigabits/sec over a 10 gigabit bonded interface (5x to 10x faster, depending on the bonding mode in the NAS and the PC). So the bonding in the NAS isn't doing anything to improve your performance.
It does no harm though, and I'm glad that you have it working again.
FWIW, I am getting faster speeds without bonding between an RN526x and a Windows PC with a single Asus 10Gbase-T card - though I'm still not saturating my 10Gbase-T connection. The PC is several years old, and I think I'm running into it's performance limits.
