Hello Aaron,

You could check to see if the CentOS 7 system is using disk encryption, e.g., if the
following command return 1, then it would mean encryption is in use (which can be
an issue with FreeSurfer).

$ cat /proc/sys/crypto/fips_enabled

If it returns zero, it could be an issue with a system library like glibc on CentOS 7.5
(that does not happen on older versions of  CentOS).

Either way, this is not your doing ;-)
