A couple ISIs, HAMs 5 & 6, and HEPI ETMX, have accumulated some saturations on inertial sensors but these were not at the time of lock loss.

Checking the offload drive to HEPI at the ETMs showed that we still had ~100,000 nm before hitting the ETMi_ISCINF_LONG 250000 limit.  Also, the cartesian positions of HEPI still seemed to be comfortably moving as directed.
