i did some more research on that. there seem to be some broken files in the
gluster-mountpoint. whenever you stat them, the mountpoint disconnects:
# ls -lisa
./8634:
ls: cannot access ./8634/copy: Software caused connection abort
ls: cannot access ./8634/random.part: Transport endpoint is not connected
ls: reading directory ./8634: Transport endpoint is not connected
