After upgrade from 12.3 to 15.1. Maybe it's some kind of debug info which was not disabled in 15.1. There is such high volume of that log dumped to messages file that, I had to filter the logs with match "!rts_commit_proposalmput" so I could actually read through messages file and found any other usefull information that I needed.
