<-------------------------Exception end---------------------->

Problem Description: Searching doesn't work anymore, list of random album doesn't work
Troubleshooting Steps: After a week of usage when activating "Clean-up database" action
Playback Application and version: Doesn't matter
Subsonic Version: 5.2.1 (build 4427) – March 4, 2015
Server Version: jetty-6.1.x, java 1.8.0_06, Linux (76.5 MB / 145.0 MB)
Hardware Platform: Linux LINUXIUMONE 3.0.36+ #1 SMP PREEMPT Fri Nov 15 22:44:22 EST 2013 armv7l GNU/Linux
Java Memory Limit: 150M (i tried to increase this value, didn't seem to matter)
Problem Filename: Doesn't matter
Output from ffmpeg -i: Doesn't matter
Last ten log file lines: Nothing interesting

When I stop Subsonic, delete db files, restart Subsonic and then rebuild the whole DB, things work normally... for a first couple of days. Then the same issue arises again. I can still use Subsonic, but search is broken, the list of random albums is broken. It seems that the DB gets broken partially. I'm getting the exception above when I try to clean up the DB (Settings -> Media Folders > Clean-up database)

Anybody, any idea?
