Android App. Help - Music Cache Settings Ignored?

[seedoubleyou]

Platform - Android 2.2
Phone - HTC Inspire
External Storage - 8GB MicroSD
ROM - Stock/MIUI/Cyanogen 7.3 Stable

On any of the aforementioned ROMS, with my Subsonic 4.x personal server, I have attempted to set the Music Cache settings within my Subsonic App to *only* cache 100MB of music, and to only download 1 song at a time.

I currently do not use Subsonic as my primary music player on my phone, but instead have a subset of my collection stored on the /Music folder of the SD card. I do however use Subsonic while at work or home to listen to my entire home collection via wi-fi.

Several times now I have found my Subsonic playback stopped due to my SD card being full. Today it occurred and using Astro File Manager's SD usage tool, I discovered my Subsonic music folder using 475MB of space with 0 available.

I the fact that the Subsonic app ignores its cache and download settings a known bug or does my conservative usage of it make me a pioneer in discovering this issue?

Any help and solution would be appreciated as a donating member of Subsonic as my phone does also get rather peeved when there is 0 space left on the SD card because of this.

-Cheers!
