Thanks a lot for the feedback, and top output. So it seems that swappolube (possible in combination with power-kernel) could cause some problems (myself I am using swappolube with suggested settings on stock PR1.3 without any problems, also using 300secs buffersize). Total memory left is quite low according to the top output, and this is probably the reason for the out of memory message. Could you resume playback after the memory error message?
