A new system option disable_shared_socket added

You can now prevent Fluentd from creating a communication socket by setting disable_shared_socket option (or --disable-shared-socket command-line parameter).

This option is useful, in particular, on Windows when you do not want Fluentd from occupying an ephemeral TCP port. Read the documentation for details.

Enjoy logging!
