Clojurians Log v2

Hi, i am trying to start a crux node when my ring app is launched. I use lein ring uberwar and deploy it with tomcat. My ring config is

:ring {
                   :handler app.core/app
                   :init app.core/start-app!
                   :destroy app.core/stop-app!
                   :servlet-name "ehdsicts2_servlet"
                   :servlet-class "ehdsicts2_servlet"
                   :resources-war-path "WEB-INF/classes/"
                   :uberwar-name "ehdsicts2.war"}

the start-app! function start the crux node like

(defonce node (atom nil)); (start-node "crux-store"))

(defn start-node [storage-dir]
  (reset! node
          (crux/start-node {:crux.node/topology '[crux.standalone/topology
                                                  crux.kv.rocksdb/kv-store]
                            :crux.standalone/event-log-dir "/Users/ouvanous/ehdsi-cts/crux-store/eventlog-1"
                            :crux.standalone/event-log-kv-store 'crux.kv.rocksdb/kv
                            :crux.kv/db-dir (str "/Users/ouvanous/ehdsi-cts/crux-store/db")}))
  nil)

(defn stop-node
  []
  (.close @node))

While using it as a jar, everything works correctly but when deploying it on tomcat, tomcat is crashing and i can't find any useful inofmration on what the problem can be ... May b e someone here know what i miss here? I did post also this question on #crux channel but it is not really related to crux itself as this works outside tomcat. Any tip would be very appreciated Many thanks and have a nice day!
