I am running an application that uses log4j version 1.2.9. The application
is running on Java 1.5.0.9 for Linux 64-bit version. After minutes or hours
of running and logging, log4j stops logging. The console shows the
following message, which partially explains the reason:
log4j: Hierarchy threshold set to [OFF].
log4j: Could not find root logger information. Is this OK?
log4j: Finished configuring.
But why does this happen? Since this information is printed from the
PropertyConfigurator, It looks as if log4j were re-configuring, even though
I am NOT using the configureAndWatch method, and the log4j.properties file
was neither touched nor changed.
My log4j.properties:
# enable log4j debugging, and set threshold=ALL (see bug 10598)
log4j.threshold=ALL
log4j.debug=true
# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=ERROR, A1
log4j.logger.http=WARN, HTTP
# see bug 10603: http should not inherit appenders, etc, from root.
log4j.additivity.http=false
log4j.appender.A1=org.apache.log4j.DailyRollingFileAppender
log4j.appender.A1.File=logs/error-${port}.log
log4j.appender.A1.DatePattern='.'yyyy-MM-dd
# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d{DATE} %x [%t] %-5p %c %x -
%m%n

I hope you can help me on this issue,
