Segfault calculating frequencies

I've successfully run an NWChem DFT geometry optimization, and would now like to calculate the vibrational frequencies, but I get a segmentation fault during the frequency calculation. My input file is at the end of this message. When I run the calculation, I get...followed by a lot of binary digits. I can't tell what's going on, whether NWChem is running out of memory, and I have to put an explicit MEMORY directive in the input file, whether I'm running out of memory on the nodes, and I have to run on ones with more memory per node, or whether something else is going wrong. Can someone help me sort this out?

Here's my input file.
