Hi, The FreeBSD NFS server is broken when handling multiple connections for NFSv4.1/4.2. It incorrectly binds the back channel to a new connection when is sees an RPC with Sequence in it (almost all RPCs) and might send a callback on the wrong connection. I have a fix, but it won't be in a release until 12.3/13.1 (months away) It can be found in FreeBSD Bugzilla PR#254560. In the meantime, avoiding use of the "nconnects" option on Linux client mounts to FreeBSD servers should avoid the problem. Thanks go to Ben Coddington @redhat for diagnosing this and testing the patch. rick
