Confirmed, this is incredibly annoying. In my case, it's coming from PHP. I've got 44k of such messages in my auth.log file that covers just the last 3.5 days, and 16k of those were actually "repeated x times" messages! All coming from php or php7.0 (both pointing to the same php7.0-cli binary). I believe this is because I use php-mongodb extensively, which uses libsasl2-2.
