This is #1087900 in src:linux and fixed in 6.12.8-1. I'm reassigning and merging the two bugs. *But* that said, I strongly encourage you to switch to a systemd running system for your nfs server. We still ship the init scripts in the packaging, but for instance you do not start with them the more advanced client tracking daemons. The legacy tracking methods will disapear at some point upstream completely and in fact for the next experimental upload I aim to disable NFSD_LEGACY_CLIENT_TRACKING (cf. https://salsa.debian.org/kernel-team/linux/-/merge_requests/1298). Thanks for the report! Regards, Salvatore
