Audacious eats space exorbitantly, how to fix?

Question

ubuntu

Hello.
Ubuntu 14.04 on VDS. There is a Teamspeak 3 client and it has a bot that "broadcasts" music from Audacious (a playlist with online radio). The player starts under the root and eats up space (20 gigs per night). After the reboot, everything returns to the original, but rebooting every time is not an option. df/du and other commands say that /root is full, but I don't see any files of this size there. Knowledge to find them is not enough) Tell me where to dig? How to make sure that audacious does not write so much information to its unknown cache? Thank you.
