Not sure what is going on there. Can you take a look at lh.inflated and lh.white.preaparc to make sure that they don't look crazy?

Hello,
We've run into an issue with freesurfer-linux-centos7_x86_64-7.1.0-20200511-813297b (on Rocks release 7.0, kernel 3.10.0-957.12.2.el7.x86_64). It appears some runs are failing at the mris_sphere stage, but not producing any very informative errors, just repeated "singular matrix in quadratic form" at the end of mris_sphere as below. I was wondering if anyone had any suggestions for further troubleshooting please?
recon-all is being invoked in two stages, with a manual brain mask replacing /scratch0/wcoath/2217885.100/sub-11233210_ses-followup/mri/brainmask.mgz in between them. This is being managed by a python script, but I think the sequence being executed is the following:

The first recon-all (autorecon1) completes okay, the autorecon2,3 stage fails on occasion (this works for most scans). Its last output looks like this (full copy attached):
