Issue with Stacking new unit in stack existant. ICX7150 (08095F UFI)

[KevAktea33]

Hello everybody, 

I have a problem when a try to add a new unit in an existing stack of ICX7150. (08095F)

Of course, the active stack and the unit have the same version. 

The stack mount well,  but the active controller request a reboot of my new unit everytime the stack mount. 
I have try to add with static and dynamic methods. 
Here the logs of my issue :
