There is a patch in stable/13 that fixed a problem where open/create would defer to an exclusive lock request and cause a deadlock. It is commit 701eb03cc0dc in stable/13, but I do not know if it will apply to 13.0 kernel sources cleanly? I thought this could only occur when delegations were being issued by the server and, since you are not running nfscbd(8), delegations should never be issued to the client, even for non-FreeBSD servers. You never mentioned what NFS server you are using. If it is a FreeBSD one, make sure delegations are not enabled. The sysctl vfs.nfsd.enable_delegations should be set to 0 on the server. --=20 You are receiving this mail because: You are the assignee for the bug. You are on the CC list for the bug.=
