I'm not saying this isn't an NFSD bug. But it might not be a problem in recent kernels. If I'm reading your reports correctly, you have not tested with 6.12 or newer. 6.1.anything is based on a two-year old code base. Any fix we create for this issue must be applied to the upstream Linus kernel first. Indeed, a fix might already exist somewhere in upstream. By upstream, I mean the "master" branch in this repo: https://git.kernel.org./pub/scm/linux/kernel/git/torvalds/linux.git Therefore the first task is for you to confirm by testing that this branch either still has this issue, in which case we have to troubleshoot further; or does not, in which case you can bisect to find the upstream fix that needs to be backported to the LTS kernels.
