It might be helpful to have more context around your issue.
What action and/or NiFi component are you using when the exception occurs/
What NiFi version are you using?
Can you share the entire error log from the nifi-app.log?
Thanks,
Matt

Hi @MattWho i just kill the process that was using nifi in this particular node and then restarted the service.
That's all.
Thanks
