Unexpected exception java.lang.OutOfMemoryError: Java heap space

[simoncn]

Ok, then the next step is to increase the heap space further by changing the value in your minimstart.conf file to -Xmx512m.

I noticed from your crash dump that the failure occurred while processing a playlist. If you have a lot of large playlists, this will increase memory consumption and could be the reason why you need a larger Java heap.
