Hello Tech-Talk,
I’m running into an issue where one of my IOCs behaves normally after a reboot, but after several days of uptime all PVs begin to
flicker — they alternate between their correct values and LINK INVALID.
Some details:
-
Rebooting the IOC clears the issue temporarily, but the flickering returns after a few days.
-
This affects
all PVs in the IOC, not just specific ones.
-
I’ve observed the problem using
camonitor as well as in client GUIs (CS-Studio).
Please advise thank you,
Alex
