Hello !
Here is my error on a 18.04 64LTS player (with distant cms 1.8.0, same with 1.8.3) :
terminate called after throwing an instance of ‘boost::exception_detail::clone_impl<boost::exception_detail::error_info_injectorboost::property_tree::ptree_bad_path >’
what(): No such node (collectInterval)
EDIT : seems OK with 1.8.11
