What you expect to be happening.

What is actually happening?
- zerotier-one_x64.exe uses ~5% on AMD Ryzen 9 3950X, which causes fans to speed up
Any steps to reproduce the error.

thanks for reporting. Are you joined to any networks? Does it do it if you leave all networks? Do you have any SSO-enabled networks?

visuve commented 6 months ago

I have joined several networks, but all of them were/are inactive. None of them had/have SSO.

I'm experiencing a similar error, zerotier is hogging the cpu while hogging the network, maintaining 80Mb/s, zerotier doesn't have any ongoing connections.

same problem, drains the battery within no time - only way to stop it, is to deactivate the service it does not make a difference if a joined network was activated or deactivated
