The old ones are Bullseye, the new ones are Bookworm. :-P Also, for giggles, I tried installing the Bullseye 1.3.4 packages on Bookworm. Somewhat surprisingly, that did work. But it didn't affect the issue at all. I guess that might imply that the change is something to do with the bits of NFS built into the kernel, rather than the nfs-kernel-server stuff? Operating at the outer limits of my knowledge here! FWIW, the kernel is 5.10.0-25-amd64 on the old machines and 6.1.0-11-amd64 on the new ones. This does make me think I'm going to have to reinstall those Bookworm servers with Bullseye, at least for now. Unless maybe somebody here who knows a lot more than me has a brilliant idea.
