You can enable DEBUG level for the logger to see detailed logs. Browse to the 'config' folder of the Serviio installation, which is at :
log4j.xml in config folder and change this:
<category name="org.serviio"> <priority value="INFO"/> </category>
<category name="org.serviio"> <priority value="DEBUG"/> </category>
Read the result in
serviio.log in 'log' folder inside Serviio installation directory. Make sure to revert the change back later otherwise your log file will be huge.
If the file is too huge and your problem is not related to library updates, you can filter those out.
