We are upgrading to match your versions, will retry and let you know
Is it possible that this only happens with the default plugin=NULL
argument to readRAST6(), and you have a GRASS GDAL plugin, so it gets
auto-found and used? Does it still happen when plugin=FALSE?

We're using
rastdum <- readRAST6("nomdum",cat=F,ignore.stderr = T)
(on a ubuntu 8.10 machine and R 2.9)
within a for() loop of hundreds of iterations.
At some point (ca. 199) we get an error
"Too many open files"
and suspect that this is because readRAST6() is opening
and not closing files. Is this a bug?
Possibly, but a complete sessionInfo() would be necessary - the versions of
the packages involved may matter. Does this reproduce with readRAST6() in a
loop reading say the same raster? I've run 300 reads of spearfish
elevation.dem without seeing problems for:

I remember having
a similar problem with writeGDAL() on a win machine a long ago,
but that problem was fixed.
Thanks
