ADAndor IOC Restart Issue: Camera Handle Already Claimed After Ctrl+X Termination

["Kim, Kuktae via Tech-talk" <tech-talk at aps.anl.gov>]

Hello,

I am currently developing an areaDetector IOC using the ADAndor module for the Andor iXon Ultra 888 CCD camera. We are using procServ for process management and telnet access.

When restarting the IOC, I do not encounter any issues if I type exit in the iocShell or press Ctrl + C. However, when I press Ctrl + X, I receive the following error message upon restarting the IOC:

andorCCDConfig("CAM", "/usr/local/etc/andor/", 9059, 0, 0, 0, 0, 0)

andorCCD:AndorCCD: initializing camera with handle 100, installDir: /usr/local/etc/andor/

andorCCD:AndorCCD: camera with handle 100 not available (already claimed?)

2026/03/04 18:46:02.652 andorCCD::AndorCCD camera not detected!

We are currently using:

• EPICS Base: R7.0.3.1
• ADCore: R3.10
• ADAndor: R2-8

Could you please provide any advice on what might be causing this issue? It would be greatly appreciated. Thank you.

Best regards,

Kuktae
