[phenixbb] phenix.refine abort

Hi,

I am trying to refine a protein with 60 chains (a T=1 virus; 5-3-2
symmetry) and each chain has 520 amino acids. I am using version 1.9
(Release tag: 1692). The job stopped midway and gave the error below
followed by "Cannot allocate memory". I have run a similar job (i.e using a
similar sized protein) before on an older version (version 1.7) and that
had worked.
Looking at the error I can't really figure out if the problem is related to
installation or a missing module or something different about the code.

I can share my files off-list.

Here is the error:
