[logback-user] RollingFileAppender

[Ceki Gulcu]

Hello Greg,

Have you tried using a logger instead of logging directly through the 
RollingFileAppender instance? What is the rollover frequency?

By the way, it would be very helpful if you could create a jira issue 
(http://jira.qos.ch) attaching code reproducing the problem.
