We also received these errors for large unit cells with high resolution diffraction. We solved the problem by installing more memory and using 64 bit architecture.

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 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 input and output files off-list.
Here is the error:
