I can’t see anything particularly wrong. From my brief googling it says bad allocation errors usually happen because you have either:
Run out of memory.
Running too many jobs in parallel.
Assigned too much memory to each plot - default 3390.
Accidentally turned off Windows page file.
Bad memory.
From the looks of it, this error should not be occurring. You have plenty of RAM to be running two plots in parallel at 3390MB per plot (In fact, this machine should be able to run 4 plots in parallel, no problem).
After reading the answers you have given me, then my last suggestion would be to look at the windows paging file.
Another alternative is to try running the software in Linux, if error is still happening there, then its a hardware issue.
