--- Comment #3 from Graeme <graeme_ch at outlook dot com> --- Since the issue is due to my computer running out of memory, I tried adding some more swap space: fallocate -l 100G extra_swap mkswap extra_swap sudo swapon extra_swap Swap usage peaked at about 16.7 GB (plus 8 GB RAM on my system) then my computer froze. It seems that either the memory requirement is growing exponentially with some aspect of the complexity here or that there is a memory leak.
