[GitHub] [pulsar] lhotari added a comment to the discussion: Bookkeeper Direct Memory Consumption is High

GitHub user lhotari added a comment to the discussion: Bookkeeper Direct Memory Consumption is High

Enabling the Netty leak detector is a way to find out where things leak with Netty buffers (which use direct memory). Passing `-Dpulsar.allocator.leak_detection=Simple -Dio.netty.leakDetectionLevel=simple` in JVM options is a way to configure it, this solution works for both Pulsar and Bookkeeper (however the other parameter is not used).
