(I'm unsure whether NFS issues should go to tech-kern or tech-net)
I'm facing a strange NLM problem where the (Linux) client sends two unlock calls in quick succession and the (4.0/amd64) server then closes down the TCP connection without sending an unlock reply to any of the two calls. As I'm more used to RPC-over-UDP than -over-TCP, I'm not certain whether interleaving calls (i.e., sending a second call without having received the reply to the first one) is permitted. So, is this a client error or server error? If server, is it a known one? If not, I've probably make myself familiar with the NLM code again I last worked on five years ago.
