The target of the whole project is experimental. As such, we love logging because we want to know what happens. The CSCFs might print a lot of those. You can, of course, at any time change the logging level from the configuration file (the debug parameter).

Unless you can tell that there is a bad behavior, don't bother reporting them as errors. On new features we like to print a lot of information colored like crazy even if they are not errors. It helps us notice if the new code functions correctly and also it makes you aware that there is something new ;-). In a few weeks/months these logs would no longer show as they will be demoted to lower importance.

The most important thing to remember is that they should all be prefixed based on the importance, like DBG, INFO, ERR, etc and this prefix overrides the actual colors and log levels.
