    • It is normal that not all channels connect, but if a very few connect it is probably best to restart the Engine.



Restart Archive Daemon Engines:

  • To restart a specific Engine you need to know the Port.
  • Ex) 
    • Restart LCLS_9  (Port 4909)
      • http://lcls-archeng:4909/stop 
      • This will stop the process and will automatically start (~30 seconds or so)
