Bind address already in use

When another process is already using the port.

The following error occurs if the listening port is already in use on the system:
WARN FAILED org.eclipse.jetty.server.Server@34fe326d: Address
          already in use


To verify, run:
ps awux | grep -E "ConnectStandalone|ConnectDistributed"
If the port is in use, a message similar to the following appears:
automat+ 30950  6.0 26.7 4839156 2190816 ?     Sl   Oct22 230:05

Kill the other process or use a different port.
