Hello,
How to reproduce:
the machine A have a glusterfs[0] mount at /mnt/gf
the machine B use `sshfs A:/mnt/gf /mnt/gfB` to mount it.
[0] www.gluster.org/docs/index.php/GlusterFS
then under /mnt/gfB, run `dd if=/dev/zero of=zero', you will recieve [1] and
crashed. And then the /mnt/gfB is auto umounted.
the full gdb trace in [2].
I think you also can reproduce this when machine A has a not-so-fast device,
for example, a USB 1.0 disk.
-------------------------------------------------------------------
[1]
dd: writing to `zero': Input/output error
dd: closing output file `zero': Software caused connection abort
[2]

remote host has disconnected
