When I've seen this kind of problem, it has been due to a copy of the
image in the swap area getting corrupted.  If you reboot the machine,
and then try the dump again immediately, do you get the same problem?

Have you checked the error log for disk errors?  Are you running out
of swap space?  Are you doing anything different on  this machine
than the others, slip, NFS, DECNET?
