99	Parallel bug in mp_exchange4d, please update your code!	arango	arango	"There is a parallel bug in tile exchange routine '''mp_exchange4d''' routine (file '''mp_exchange.F''') when exchanging more than one array via MPI message aggregation.  I have been looking for this bug for awhile and I finally found it. This bug was initially reported in the term diagnotics by William Cabos. It was an ellusive bug since it only appeared in periodic applications.  It only affects '''ini_fields.F''' and '''set_diags.F'''.

The usage of '''mp_exchange4d''' for a single variable exchange is fine.  The bug is in the second variable."	bug	closed	major	Release ROMS/TOMS 3.1	Nonlinear	3.1	Fixed
