Bug 764671 (GLUSTER-2939)

<bug report>

Every now and then I keep getting the following error:

mkdir: cannot create directory `/home/simplicitymedialtd/ds': Transport endpoint is not connected
mkdir: cannot create directory `/home/simplicitymedialtd/ds': Transport endpoint is not connected

To make this error go away, I have to unmount and mount the directory. Seems to be related to a crash (see below log)...

Any idea why this keeps happening?
