Log4J problem with RollingFileAppender and backups

Hi, 


We are using Log4J in our J2EE application with RollingFileAppender and a number of backups. 

When the appserver and application starts everything seems to work as it should, it creates the logfile and backups after the max file size have been reached. When max backup parameters are reached the files rolls away from disk. 

But when restarting the application (ear, not the appserver) it seems to lost it's track and the the files are removed one by one, starting with the logfile.log.1. 

The logfiles can not be removed as long as the appserver is started. 

Any ideas? 

Using IBM WebSphere 5.0.2/5.1 and Log4J 1.2.8. 
Configuration and trace are avialable below.
