[GRASS5] r.series, max files open

I am trying to get r.series to produce time series stats for 365 raster
files.

It dies after opening about 254 files through. (sorry don't have the
exact error message on hand)

I assume it is running up against a max files open limit, so I haven't
looked too closely, could be something else (memory;
inputfiles=raster1,raster2,...,raster365 makes the command line pretty
long; for example), or a dumb mistake on my part.

I'm running Linux 2.4.19 with r.series from CVS.


If it is a max file limit thing, r.series should be able to work around
that.. open 200, dump them to memory, fclose all, read another 200, etc.
until all are loaded and then do the math. I would think a time series
program should be able to handle at least 8760 (number of hours/year)
records? 365 at minimum anyway.

any ideas?
