Is this a bug? Someone smarter than me will probably respond to tell me that I'm wrong, but in my nascent understanding of NFS I'd say no, although I can't quite explain exactly what I'm thinking about it. The best way I can express it is to say that while one client is already making a change on a file system more requests from the same client get queued. I believe that if you were to do the 'ls' from a different system it would not block. Ok, there's the slow hanging curve, someone else can step up and hit it out of the park. :) Doug To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
