Hi Kurt, I apologize for the late response. I have looked at the network trace. The problem stems from the broken server that claims to support fs_locations but then decides to never reply to the query. I can implement a mount option to say fs_locquery=off to handle mounts against the broken servers? However I would like to ask if the better path forward isn't to update to the knfsd where the problem is fixed? > > Best, > -- > > Kurt Garloff <kurt@xxxxxxxxxx> >
