[j-nsp] Flapping GE Module causing FEB to reboot

[Josef Buchsteiner]

Joerg,
      trust Pekka he was right spot on. Don't run diagnostic on the
      box just like that. You have to do much command before results
      are meaning full. So get in contact with jtac and they will
      provide you with a solution to your problem.
