Satish, here is our stack trace. Do you have any thoughts vis-a-vis Fande's
experience what the problem is here?  My best guess is that the local
matrix size is huge, but this code can have some very large stencils.

Treb: about how many processors have this error? Is is it just one, a few,
or tons?
