The branch stable/12 has been updated by rmacklem: URL: https://cgit.FreeBSD.org/src/commit/?id=775904f5b4ec82af9f8b536eaebe6876d2e1f412 commit 775904f5b4ec82af9f8b536eaebe6876d2e1f412 Author: Rick Macklem <rmacklem@FreeBSD.org> AuthorDate: 2022-07-03 20:37:23 +0000 Commit: Rick Macklem <rmacklem@FreeBSD.org> CommitDate: 2022-07-18 00:08:54 +0000 mount_nfs.8: Update BUGS section for NFSv4.1/4.2 If the "intr" and/or "soft" mount options are used for NFSv4 mounts, the protocol can be broken when the operation returns without waiting for the RPC reply. The likelyhood of failure increases for NFSv4.1/4.2 mounts, since the session slot will be broken when an RPC reply is not processed. This is mentioned in the BUGS section of "man mount_nfs", but there was no specific mention of the session slot problem. This patch adds a sentence for this case.
