Terminated processor thread is not disappearing.

Hi for all!

Does anybody know why terminated processor thread info (up right corner) in red does not disappear after it is terminated, the processor works fine but this red info is not disappearing for 2 weeks. How it is critical and how can I fix this as this red appearance is causing issue and everyone is questioning?

Thanks!

Welcome to the community @bhagi . I'm sure you have already tried this but can you try refreshing the page in case it did not automatically?

Hi @bhagi

This can happen when the processor is terminated but the thread is not finished. When NiFi terminates a processor it does an interrupt, once that happen it should do a graceful shutdown, but it's not guaranteed.

In any case, that shouldn't stop the processor from running again. Please see the following question:
