    Hi,
    I’m running the finance sample and when I get to the command “kamanja start -v”, I get the following after about 20 minutes:

    Should I just ignore these error messages? I’m able to run “kamanja watch output queue” successfully.

    thanks,

    Those errors are related to zookeeper. They come up from time to time and I’m not sure why. Are you able to run applications?
