Zookeeper complaining when exposing a tESBProvider service

[Anonymous]

Dear sirs,
I have an ESB web service job to expose a call to an external web service (as attached image). When running in TOS, everything seems fine. When I start the job inside T-ESB (karaf), the container's log start filling with the following exception
the exposed service url is: "http://localhost:9088/esb/geefOnderneming". I tryed to change its port but makes no difference.
Anyway the exposed services work, just the log is filling with the message and don't want to ignore WARN logs.
Carpe diem

Note:
I've checked and the port is not open - what has the ZooKeeper to do with the exposed jobs?
