Hi Piotr, Thanks for your quick response.
Below two gists with the traces for both cases: 1. Using "this.systemLog = LogManager.getLogger("LOGGER_SYSTEM");": https://gist.githubusercontent.com/joanbalaguero/a59fb664774c44535c10817900a80ed5/raw/8bb6b6a963a607f0d99105248ce32a28ad39590a/gistfile1.txt In this case logs are not created. 2. Using "this.systemLog = LogManager.getContext().getLogger("LOGGER_SYSTEM");": https://gist.githubusercontent.com/joanbalaguero/acd0a4edaf856ad34c44a196caef7bdc/raw/474febc0397b97a9b941dbd86b830149ac94ad07/gistfile1.txt In this case logs are created and content is logged into them correctly, but the hazelcast log (from "com.hazelcast") is not sent to the SYSTEM_LOG. The " log4j.configurationFile " variable is set in this way: System.setProperty("log4j.configurationFile", "/opt/ventusproxy/app/proxy/ROOT/WEB-INF/log4j.xml"); And tomcat starts with: -DLog4jContextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector The point is that for years we have been running this without issues using point 1, without getting the context from the LogManager. One more clue. As I said, this is not working fine on our new installation with Centos9 Stream, Apache Tomcat 8.5.83 and Zing JVM 11. Exactly the same code running locally on a windows 10 with Apache Tomcat 8.5.39 and Oracle jdk 11 works perfectly, logs are created and the hazelcast logging is sent to the SYSTEM_LOG. Thanks, Joan. -----Original Message----- From: Piotr P.

The automatic configuration uses `LogManager.getContext(false)` to retrieve the right logger context. Can you run your application with `-Dlog4j2.debug=true` and share the output?
