We have found a Server bug introduced with version 7.0.1 affecting log configuration.

The bug is on the "relative appenders", custom appenders provided with the Server and preconfigured in the factory log configuration file as LSRolling and LSDailyRolling.
These appenders allow you to specify a relative path for the log file in which the base directory is the one that contains the configuration file itself (instead of the JVM launch directory).

Unfortunately, upon the first manual modification (of any kind) of the configuration file while the Server is running, the base directory changes and becomes the JVM launch directory.
In practice, the log file stops growing and a new file is created and grown in a different place.
After a Server restart, the original file is grown again.

A fixed version of the Server will be released in a few days.
