Clickhouse: Address already in use error with docker image 1.1.54378

[derekperkins]

I just upgraded my application from 1.1.54370 to 1.1.54378 by simply using the new docker image. I'm now getting an error in the error log:
Error> Application: Net Exception: Address already in use: 127.0.0.1:8123

Any idea what might be causing this error?

When I rolled back to 1.1.54370, everything initialized properly.
