Server logged message line grows in length with each denied connection attempt from a given client

[JamesTGrant]

When a client attempts to connect with an incorrect password, the cooresponding server log message grows in length with each repeated report of the incident. I think this is related or the same as the following issue you previously fixed in the client: https://github.com/erebe/wstunnel/issues/242

tested using v9.7.4 and v10.1.1

Please see example log output attached: growing.txt

(the restrictions file and functionality is awesome by the way)
