system log message every second

Hi – relatively new user here.

Whenever our computer goes into sleep mode/screensaver under my wife’s login, it stalls and will not wake up. Doesn’t happen under any other user logins (go figure :). While trying to troubleshoot that issue, I reviewed the system log via YaST. I got a LOT of

Apr 11 15:25:52 linux-d8dy kernel: sr0: CDROM not ready. Make sure there is a disc in the drive.

And by a lot, I mean it is every second. I don’t have anything looking for a CDROM file that I know of. Can someone tell me what is causing this? Is there a way to make it stop?

Sounds like something is running trying to access the drive? Maybe some CD player app??
