Description

I don't know why rgw.none indexes are created so much.
To my knowledge, rgw.none index is generated when cancelling a rgw transaction.
I just assume that multiple LC processes would try to delete the same object simultaneously.

Anyway, whatever the reason is, in this situation, a list operation takes too much time to complete.
Looking at the log, it seems like it's stuck in an infinite loop.
The same keys appear multiple times.
