We can’t really help you if you don’t answer our questions.

As far as I understand you have a stack of X590s as your Core. 4x X590? Which firmware? 

[Alexey_shaverne]

I use the stack on the x590 as the core of the network. The core comes with 6 stacks x440-g2. x440-g2 stacks perform the function of an access switch. When I connected the new stack to one of the access stacks, the core went to reboot. what could be the problem?

looks like the stack failed and master initiated a complete reboot of the stack.

What version are you running.

I had a similar issue at a customer a few weeks ago with a x440g2 stack
