According to camera server's logs, network connection of POS camera is unstable in a recent couple of months.
I'm not sure it's related to the recent activities related to the cavity length measurements.
Anyway, cable connection must be checked once.
And also, it's better to replace LAN cable if the connection becomes unstable just by activities around POS table.
LAN cable might be aging such as one for the PMC camera.
Even though there was no activity around the POS table, the situation appears to have changed.
Since the camera unit itself has never malfunctioned before, we should first try replacing the LAN cable.
Attached figure and text file shows a down time of POS camera.
