Hi Rolando,<br>
<br>
Thank you for posting your logback.xml file. I suspect that for some<br>
reason logback is unable to rename some of the archives.<br>
<br>
In any case, setting the debug attribute to true in <configuration><br>
element should provide helpful clues as to what is going on during<br>
file rolling. Here is the modified <configuration> element:<br>

Hi David,<br>
Configuration is below. I'm also showing the sizes of the log files,<br>
you'll notice that some of them have sizes much larger to what is<br>
specified with the MaxFileSize parameter of the triggering policy.<br>
<br>
Thanks,<br>

That sounds strange. Can you post your logback.xml file?<br>
