Hi all,
After a few number of iterations, my simulation stops with this message.

I am running a 2.5 million control volumes case in 48 processor (750MB Ram each)

Do you know how to repair/what is the cause?

I decomposed in another machine (with 4GB RAM) and then scp the decomposed case to this one.

the output file read:
