2Gb memory problem

dear molpro users,
I am using molpro on a cluster of Sun V880 connected to a Blade 2000
"front end" machine. I could succesfully compile molpro as a 64 bit
executable, but, despite there is no problem with scratch files, I cannot
run calculations with more than 2Gb of memory (268 Megawords). I compiled the
source following all the instructions which are given in the installation
guide, and tried to see if something changed using BLAS=0 when running my
"configure" file, in order to use the Molpro Fortran blas library instead
of the system one, as it seems it is suggested in case of Sun machines. Even
in this case there's still the 2Gb memory limit.
On our machine each cluster has 8 processors with 4Gb or memory each, and
memory is shared, so in principle one should be able to use 32Gb of
Has anyone an idea of what is going on ?
Thank you very much.
