The current version of cpptraj can get very memory-hungry with very
large trajectories (in the hundreds of thousands of frames). The next
version of cpptraj (under development) will have a much smaller memory

In the meantime, you could try breaking up your analysis into separate
runs - i.e. perform ;atomicfluct' one run, 'hbond' in a separate run,
