      If you happen to have a node in your config that is down, the system log on all the other nodes each fill with 12 log messages every half second (24 messages per second). This seems excessive.

      Example of all the messages logged in 3 ms:

      I wonder if the volume of ASIO messages could be reduced in this situation.
