Can anyone help me with this topic?
There is only one way to remove debug information from the log files - decrease log level to ERROR or FATAL.
For a production server, it is necessary for a performance reasons too, so DEBUG log level can decrease performance by 3-5 times.
Anyway, I will remove this debug point for a next release.
