Samsung Galaxy S2 - Music / Audio / Doggcatcher randomly stops playing

Music or audio (including Doggcatcher) on my Samsung Galaxy S2 (Android) will play for a number of minutes and then randomly stop.

I have not be able to figure out the problem as yet. 

Possible fixes: 

Currently Testing - Soto Settings > Motion > Double Tap = Disable.
Results = This did not fix the issue. Music and podcasts still randomly stopped when playing.

Updated to new firmware.. Will be testing this over the next few days (Gingerbread.xxKH1)

I'll update this post again when I've finished testing over the next 48 hours. 

Update: It seems that the latest firmware may have fixed this as I have not had any music stop since updating.
