Logging is happening at TRACE level on Gatling 3.9.0 although it is set as "WARN"

Gatling (Open-Source)
1

Hi,
I have recently started using gatling-3.9.0.
In logback.xml the log level is set as – .
However I am seeing Log is happening at TRACE level when I am running the test from a Linux platform (Redhat 8.4 with OpenJDK 11.0.10) as a server.
In my local Windows 10 system with OpenJDK17 the log is happening fine.

My older versions of Gatling ( 3.7.2 , 3.8.3 ) it is working as expected.

Is set as what?! Valid values are error, warn, info, debug and trace.
Either your logback.xml file is broken, or it’s missing from the classpath. Anyway, it’s not a Gatling issue/regression but something you’ve broken on your side.

You can check for yourself that the official demo projects work as expected.

Official demo project is working as expected.

Not sure if some deprecation issue or not. I will check my script and update accordingly.
First few part from the log is coming as :

GATLING_HOME is set to /root/archan/gatling-3.9.0
