Sooner or later in the previous few days I get an lsof warning for a shell script that is been operating each 60 seconds for over a 12 months and has by no means returned this warning earlier than. The one issues I can consider are I ran df -h command yesterday to verify on quantity utilization, and I additionally restored an utility from a Time Machine backup just lately.
lsof: WARNING: cannot stat() apfs file system /Volumes/com.apple.TimeMachine.localsnapshots/Backups.backupdb/iMac191/2024-10-20-002526/iMac191_1TB - Information
Output info could also be incomplete.

I can ignore the warning utilizing the -w flag however I’m extra curious what has modified on my system that’s inflicting it to look moderately than simply ignoring this modification. To achieve data. I do not see a lot point out of this error on macOS. I additionally do not wish to exclude different warning messages I’d obtain.
The script is just operating lsof -i for web connections so it is complicated why lsof is studying the native file system in any respect. I am unable to use the -e flag ( -e /Volumes) as a result of it is not carried out for macOS AFAIK, solely Linux.

UPDATE
I did a secure boot and reset PRAM and no the warning message is gone regardless that the identical two TimeMachine volumes are mounted
