I have an nfs-share that I access via automount in /net/<host>/<share>.

The following scenario:
- cd /net/<host>/<share> inside tmux
- Do stuff
- S4 the laptop and take it to work the next morning
- Resume and the tmux session hangs infinitely
- Kill all shells belonging to the tmux session
- tmux server process hangs in state "rpcrec"

It's bad enough that there apparently is no path for NFS to fail
and reanimate the shell that accesses the share.

But the really bad problem is, that tmux in rpcrec state is not
killable. I.e. not kill -9 able. And as long as that process is around
any new tmux server I try to start just hangs.

For this killable stuff there is the 'intr' mount option. See also the 'soft' mount option if you don't want NFS to wait indefinitely for a lost server.
man mount_nfs describes this all.

Regards,
Ronald.



My only recourse so far is a reboot.
