This seems to be the real issue: SEVERE: Mapped exception to response: 503 (Service Unavailable) javax.ws.rs.WebApplicationException: java.io.IOException: java.lang.RuntimeException: java.lang.OutOfMemoryError: Direct buffer memory
If you're using a Sun JVM, you can change that by using the option -XX:MaxDirectMemorySize=<size>. By default, the size is 64M.
