The warmer just tries to load norms/docValues/etc. for all fields that have them enabled ... so this is likely telling you an IndexReader would also hit OOME.
You either need to reduce the number of fields you have indexed, or at least disable norms (takes 1 byte per doc per indexed field regardless of whether that doc had indexed that field), or increase HEAP to the JVM.
