System Logs max events

Does anyone point on what am I missing?

I made sure the logback.xml has 50000 max events configured for appender but the log file just keeps growing

Can you upload your actual logback file?

The pruning of log events is on a time based debounce, so it's never going to run faster than once per minute. If you've got an extremely spammy logger, I could see you pushing so many events so fast that the time based cleanup is never able to "catch up" and keeps getting further and further behind, maybe?

Okay, looks vanilla. So what logger(s) are spamming your logs to hit 18 million events in any reasonable timespan?
