 - stop servers also check for errors at startup( in case it was running with an older version)
 - hostname cmd failed when connecting to servers in update mode (ctb, moench, jungfrau, eiger)
 - missingpackets signed (negative => extra packets)
+- 10g eiger nextframenumber get fixed.
+- stop, able to set nextframenumber to a consistent (max + 1) for all modules if different (eiger/ctb/jungfrau/moench)
