The other problem; out of memory during LU factorization

$

Hello, everyone
I have a little different problem with others
First, my error message is similar with the others

"Failed to find a solution.
Out of memory during LU factorization.
Returned solution is not converged."

The real problem is, however, I upgrade my computer RAM from 32 GB to 256GB to solve quite large and complicated models. Meanwhile, the model that I calculated was only 5M DOF. It seems to be solved within 64GB. I believe that. Furthermore, the error ocurred at around 30GB or 50GB (according to different solvers)

Here is the question. Why did the error happen at 30 or 50GB even though my computer had 256GB RAM.

ps. I used AC/DC module/ magnetic field/ frequency domain only
