CCL: Molpro and gmainv1 failure

          Hi all,

          I have a linux machine with 4GB of memory and I'm trying to execute a job with this memory limit but I can't.  The error message is the following:

Failure in attempting memory allocation of 180230002 words (1375 Mbyte)
This error has been generated by the operating system,
and may be the result of insufficient system memory or paging space
In order to avoid the problem in the MOLPRO context,
consider also reducing the requested memory through
the MEMORY input command, or the -m command line option
gmainv1 failure to allocate 180230002

            I already had done a small search for similar issues and I had found that a possible problem is the datasize and stacksize limits, but the problem stills even after changing these values to unlimited:
#ulimit -acore file size        (blocks, -c) 0
data seg size         (kbytes, -d) unlimited
file size             (blocks, -f) unlimited
max locked memory     (kbytes, -l) unlimited
max memory size       (kbytes, -m) unlimited
open files                    (-n) 1024
pipe size          (512 bytes, -p) 8
stack size            (kbytes, -s) unlimited
cpu time             (seconds, -t) unlimited
max user processes            (-u) 7168
virtual memory        (kbytes, -v) unlimited

       How can I solve this problem?
