Unable to turn off/restrict logging for one of the ApacheDS class

Question

I am using the following log4j2 configuration to restrict the logging from one of the ApacheDS classes to ERROR and lesser.

<logger level="error" name="org.apache.directory.server.core.partition.impl.btree.jdbm.JdbmIndex">
     <appender-ref ref="ARTFile" />
</logger>

The messages from this particular class are still getting logged at DEBUG level. A similar setting for the following package worked.

org.apache.directory.server.core

Please help.

Here is the complete configuration.

If your goal is to restrict the log level it may be better not to specify the appender-ref: that way the restriction applies to the root logger and all associated appenders. In the configuration snippet you showed, the restriction only applies to the "ARTFile" appender.
