The JNA driver allocates direct ByteBuffers, however there seems to be some indication (see http://stackoverflow.com/questions/1744533/jna-bytebuffer-not-getting-freed-and-causing-c-heap-to-run-out-of-memory) this might result in Java to run out of direct memory because the garbage collection (which frees the ByteBuffer and therefor the allocated direct memory) might not run in time.

Consider pooling the direct buffers.

Pooling might also have some additional side effect like better performance (less allocation).
