Can you confirm, that the setsid action is really executed for the session collection and that it happens before modsecurity_crs_16_session_hijacking.conf? Given your description of the setup, it should be alright, but somehow there is an issue. If the creation of the collection fails, then there should be an additional error, so I think setsid is not happening.
