Debugging Scanner

Hi, for the last few years my scanner hangs consistently. I have to stop and restart it a few times till it finds my new music.

What's the best way to debug? It seems that the scanner.log file isn't updated anymore (at least for me, last update to the file was July 2012)

For reference:
Logitech Media Server Version: 7.8.0 - 1386246861 @ Fri Dec 6 19:17:50 PST 2013
OS: Netgear RAIDiator - EN - iso-8859-1
Platform: i686-linux
Perl Version: 5.8.8 - i486-linux-gnu-thread-multi
Database Version: DBD::SQLite 1.34_01 (sqlite 3.7.7.1)

Thanks,
Dave
