> Our production bookkeeper cluster has hundreds of bookie instances, and i should roll restart all bookie instances to add those JVM options. The OOM only occurs when auditor starts to scan all ledgers, and the JVM direct memory monitor shows no direct memory used and the bookie instance with low load. The `-Dio.netty.leakDetectionLevel=advanced -Dio.netty.leakDetection.targetRecords=30` settings might have a major performance impact, so it's not recommended to put the settings to a production cluster. It's better to first test the impact of enabling the leak detector in a test environment before using the leak detector setting in production. -- This is an automated message from the Apache Git Service.
