The code in clnt_vc.c was exactly what made me wonder about treatment of ERESTART. > problem. I'll take a look at your patch tomorrow.

In my case the process was also stuck in unkillable running state because the process never returns from the syscall. Unfortunately amd itself seems to handle NFS requests for its own top-level mountpoints only via UDP. At least I haven't found a way to do so without hacking rather convoluted amd code. > I'll look tomorrow, but it sounds like you've figured it out.
