Comment (by jcardona):

 The {{{Destination Host Unreachable}}} error appears to be temporary
 problem:  retrying the '''same node''' after some time will work.  Also
 the UUT can still ping other nodes when one destination becomes
 {{{Unreachable}}}.

 This seems to depend on (1) the dense radio environment or (2) the number
 of nodes in the mesh.  The fact that this has also been observed on OLPC
 tesbed (13 nodes) during daytime seems to indicate that (1) is a necessary
 condition to trigger this behavior.  Suggesting retest in shielded
 environment with a large mesh to confirm this.
