If the external memory card is too much loaded , this happens.or if there is too much application running , this may happen . so delete some large application and run one application at a time. Pertaining to messaging , that would have happened due to tower problem .... if it happens continously , then the tower detecting signal sensor would have been faltered . go to service centre with ur mobile and get it rectified
