NiFi Load Balance Error

New Contributor

Hi all,

I'm running a NiFi cluster with 2 nodes,

I met this error, it loop infinity. I don't know the reason, my current solution is restarting clusters. Anyone can explain and help me please. 

Error Message:

Hi @trangnd !

 

Did you ever find a solution for this please? 

 

For us, we usually overwrite the flow.xml file or just do a restart, but it would be nice to know why this is happening.

 

Thanks!
