This is true for FreeBSD-6.4 and FreeBSD 7.1. (with and without kernel support for NFS locking). Since NFS-Serving is the major task of our FreeBSD servers, this error is a show-stopper for us, which prevents us from further upgrading the operating system. FreeBSD 6.3 and 7.0 do not show such behaviour. >How-To-Repeat: Mount a filesystem from a FreeBSD-Server on a HP-UX 11.11 machine via NFS V3. Try to lock a file (that works) then try to remove the lock. You'll wait forever... I found the problem with my (HP-UX)homedirectory on a FreeBSD NFS-Server. The login shell locks .profile and hangs after the last statement of .profile. Wireshark shows a continuing stream of "NLM V4 CANCEL MSG"es from the client to the server, which will never be answered. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
