Thank you , Peter. There are already 2 GB log files(server.log+wrapper.log), and 120G available in this partition. The timestamps for the log messages are correct. Here is the code of FILE appender: <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender"> | <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/> | <param name="Target" value="System.out"/> | <param name="Threshold" value="INFO"/> | | <layout class="org.apache.log4j.PatternLayout"> | <!-- The default pattern: Date Priority [Category] Message\n --> | <param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n"/> | </layout> | </appender> Is it right? Is there some interference from wrapper side? Thanks View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4228714#...
