      I'm only aware of one problem (maybe two) since I upgraded to
      the 2 GB flash drive / CentOS 5. The node stopped responding
      once a few months back. I power cycled it and it has fine since.
      The other instance was when I realized that there was no outgoing
      audio to a reflector that I was connected to. Disonnecting and
      re-connecting took care of it.

      Done... once I stopped trying to do it as repeater!

      Done.

      I assume the flash_sync can be skipped with the 2 GB flash drives?
      I just rebooted after doing the above.

      Thanks for the update!
