Linux is less picky about renaming files with open handles. However,
this does not mean that your log files are not being clobbered under
Linux. You should probably enable prudent mode [1].

It seems that you are ignoring my remarks about setting the context
name within the config file. It's OK as ContextJNDISelector provides
an alternative solution although ContextJNDISelector is an overkill if
you are going to share the same configuration file.
