Memory Error

Just Got Here
Dear all,

I'm trying to run a geometry optimization of a quite big system and I'm getting the error movecs_write: ma failed 9955. I read that this problem is due to the Memory I'm asking for the calculation.
Is the first time I'm trying to run a nwchem calculation and I don’t' know how the memory specifications should be.

The computer I'm using has the following specifications:
48 Cores x Node and 1.880 Gb x Core.
I'm running the calculation using an entire Node.

Is there any rational way to consider the memory specifications?

Pleas find attached below the Input I'm using.

Thank you.

Best regards,
Gerard
