> For some reason we are no longer able to update a parameter on our nifi cluster. That's not related to some processor/controller that can't be stopped because : 
> 1 - It happens on all of our parameters contexts (different dataflows/PGs)
> 2 - As shown in this [screen record |https://www.screencast.com/t/N5ard5eW2AQP] even with an empty  freshly created parameter context we can't add a new parameter. 
> In both cases we get this error 
> !sc_error1.png!
> !sc_error2.png!
>  When we restart our cluster it works then after few hours it happens again
