I believe the problem with this is that the connection is reset when
there's no traffic which causes sshfs to hang. This is exactly what
happens if you leave a ssh terminal open and walk away. Since sshfs
simply uses ssh, it will behave the same way. There's many ways to
workaound this.

Gutsy? I have the same problem in Ubuntu 11.04. There's also an ugly

Normally I would agree, except NFS is ages old and does not freeze
applications/the entire operating system when the Network File System goes
away. The same applications that freeze when sshfs mounts go away do not freeze

I just wanted to add another work-around if you find yourself with a

I had one, did a forced, lazy unmount, but a number of processes were
still blocked (terminals, gvim, nautilus). The solution was to kill -9

sshfs makes any remote SSH-accessible file accessible like a regular
local file, with the same ancient C file I/O API blocking functions

But fundamentally these remain remote files, subject to network latency
and timeout issues,

My problem with evince (Comment #21) was indeed caused by it trying to
