Lorenzog,

usually there are errors logged in these files - if they get big it should ring some alarm bells. You can view them using a text editor, I would try to find out the reason for these errors.

As I don't know if writing the logfiles can be turned off or not (and don't remember such an option) I would suggest using a tool like DelAge32, writing a batch file and calling this by a (Windows) scheduled task to get rid of the files.

DELAGE32.EXE C:\DNN\Portals\_default\0\Logs\*.* 10

would delete all files older than 10 days from that folder.

Best wishes
Michael

Thank you, I edited the log4net file in this way:

<log4net threshold="OFF" />
