One error message is about an 'already queued' 
com.redhat.rhn.taskomatic.task.SummaryPopulation task, but in 
/etc/rhn/default/rhn_taskomatic.conf and 
/etc/rhn/default/rhn_taskomatic_daemon.conf it appears only one time and 
Oracle RHNTASKQUEUE table is empty

The other message is about 
com.redhat.rhn.taskomatic.task.CompareConfigFilesTask 
java.lang.NullPointerException, but I don't understand which is the 
problem; I've tried to enable debug loggin, but I'm not able to do it. 
I've add this line to /usr/share/rhn/classes/log4j.properties

log4j.appender.TaskomaticAppender=org.apache.log4j.FileAppender
log4j.appender.TaskomaticAppender.file=/var/log/rhn/rhn_taskomatic.log
log4j.appender.TaskomaticAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.TaskomaticAppender.layout.ConversionPattern=[%d] %-5p %c 
- %m%n
log4j.logger.com.redhat.rhn.taskomatic=DEBUG,TaskomaticAppender
log4j.logger.com.redhat.rhn.task=DEBUG,TaskomaticAppender

but debug still not active for CompareConfigFiles task; also if I add:

log4j.logger.com.redhat.rhn.taskomatic.task.CompareConfigFilesTask-13=DEBUG,TaskomaticAppender

or

log4j.logger.com.redhat.rhn.taskomatic.task.CompareConfigFilesTask=DEBUG,TaskomaticAppender

or

log4j.logger.com.redhat.rhn.task.CompareConfigFilesTask=DEBUG,TaskomaticAppender

no way to enable debug mode ...

Someone could help me ????

Thank you in advance,
    Marco
