title: jBoss changes log level itself
body: <p>We've observed quite a few times now, that our production jboss (EAP 6.1), changes its log level to DEBUG by itself.</p>
  
  <p>This allways happens after the application runs a few days without any problem. But then, the log level drops to debug for all categories (e.g. Hibernate debug log)
  We also have a size rotating file handler, with a configured log file size of 100MB. But if the log level drops, the files get larger and larger (last week, we have a 6GB log file)</p>
  
  <p>Till now, we have no idea what happens or what could be the cause.</p>
  
  <p>Perhaps someone out there has an idea, where to start investigating?</p>
