Last night at 23:35 Thu 01may2025 PDT the lab dust monitor EPICS IOC stopped running, causing EDC disconnected channels.

I logged into the IOC this morning, it was reporting serial comms issues with the LAB2 and LAB3 dust monitors, but I think that is expected (logs shown below). No logs seen about LAB1 or the IOC itself.

I restarted the IOC which cleared the EDC disconnections. CS_DUST_LAB1 is sampling again, albeit currently with zero particle counts. LAB2 and LAB3 are shown as "NOT IN USE".
