You can start by checking the client, to make sure it hasn't run out of memory or hung. Also check the xbmc.log/kodi.log for errors. A @logfile might also be useful.

Try running "C class" where class is one of movies, tvshows, addons etc. to try and pin down which class is the problem - the console information should already give you an indication of how far it is getting before hanging.
