Lsof: no pwd entry for UID 1000000

I found more than 100000 entrys in lsof with
“no pwd entry for UID 1000000”.
And the number grows fast.
Is this correct?

Yep, that’s normal. “lsof” attempts to resolve the name for any uid it sees but those uids don’t have any name associated with them, so that line shows up.
