Certainly sounds like something halted... usually the startup process ends with these statements:
info: [sounds] Sounds OK
info: [themes] Compiling templates
info: [themes] Successfully compiled templates.
info: NodeBB attempting to listen on: 0.0.0.0:4567
info: NodeBB is now listening on: 0.0.0.0:4567
info: [meta/css] Done.
info: [meta/js] Successfully minified.
info: [meta/js] Retrieved Mapping.
info: [meta/js] Compilation complete
info: NodeBB Ready
The "now listening on" and "Ready" are key
Try disabling all plugins (
./nodebb reset plugins), and re-activating them one by one.
