Hello Vaishak,

please see:

https://bitbucket.org/einsteintoolkit/tickets/issues/2473/out_vars-incorrectly-uses-grid-fucntion

for a fix (in branch rhaas/outputgroupactive of Carpet). It does turn
out to indeed be a bug, related to the interaction of parallelization
using MPI, using multiple coordinate patches and asking for HDF5 output
of a grid array.

Yours,
Roland
