 > r.series with the same number of input maps should fail with the same
 error. r.hants has been derived from r.series, and both modules have the
 -z flag (Don't keep files open) which should avoid this problem.

 Sorry, the -z flag does not help here because r.hants creates a new output
 map for each input map, and these need to be kept open. For 600 input
 maps, the hard limit of the number of open files is usually exceeded.
