After executing /etc/init.d/ejabberd start everything starts ok, but I got this message in logs: I(<0.37.0>:ejabberd_app:72) : ejabberd 2.1.7 is started in the node ejabberd@localhost and after /etc/init.d/ejabberd stop: I(<0.37.0>:ejabberd_app:89) : ejabberd 2.1.7 is stopped in the node ejabberd@localhost
I assume upstream forgot to update the version number in certain places
Thank you for report. Fixed in 2.1.9.
