VACSTAT reports BSC3 and HAM6 issues
At 21:58 VACSTAT issued a BSC3 alert, which looks like it could be a sensor spike. 1 minute later PT110 (HAM6) sensor went offline to flat 0.0Torr.

BSC3 sensor glitch at 06:59:43, could be related to HAM6 issue, these are the same type of gauge. I restarted VACSTAT at 08:05 to clear this, it is again running with HAM6 PT110 DISABLED.
