Bug is confirmed. The statistics messages are not displayed immediately: one have to wait some time or stop the rochtunnel tool.

Analysis:
The system bufferizes the messages for performance reasons, so they are not written to the files immediately. One have to wait some time or stop the rochtunnel tool for the messages to be flushed in the log files.

Solution:
The problem may be definitively corrected by forcing the system to flush the statistics messages to disk after every new line.
