You don't give us enough details to do anything much more than guess but
I am curious what is meant by rpciod cpu usage is very high thinking
that it might have something to do with this issue.
I don't often detail things such as noatime, rsize, wsize, hard (in
fact, I haven't used hard nfs mounts as I seemed to recall some hanging
issues.
