 I have a linux machine(RHEL5 system,Intel(R) Xeon(R) CPU E5335) with 12GB of memory and I'm trying to execute a job but I can't.  The error message is the following:

Failure in attempting memory allocation of 500230002 words (3816 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 500230002

I already had done some search for similar issues and I had found that a possible problem is the datasize limits, but the problem stills even after changing these values to unlimited. And I had update the kernel to the latest stable version(, but it is also no use.

Would you help me to solve it? Thanks.
