Comment 17 for bug 234480

Given that this bug has hung around for a couple of years without much action, I thought I would have another dig around to see if I could find anything useful.

I eventually came to the conclusion that this is actually a kernel issue. It seems that the Gutsy kernel (2.6.22) returns immediately with a "No route to host" message when the server is unavailable, while the later kernels return after a significant delay with alternative error messages.

I also found this post: http://linux-nfs.org/pipermail/nfsv4/2010-February/012112.html that discusses this issue. It indicates that we might see some improvement in kernel 2.6.33.
