B1537 increased RAM consumption?

Wanted to report increased RAM consumption with B1537 EA on a QNAP HS-264, despite from having zero performance issues.

On booting process completed, roon´s server process is shown to already consume 4+GB of RAM managing a library of 60k tracks, which is already more than with previous builds (rather in the region of 3GB). Some hours into using it, RAM consumption is increasing above 90% of available RAM. RoonAppliance alone is responsible for eating up almost 7GB of RAM.

No performance issues, though. Is it a silent memory leak maybe? Haven’t notices any increased RAM consumption for more than 1 year.

The issue vanished after 2 days and RAM consumption is back to normal. No changes from my side except from a handful of Qobuz albums removed from the library.
