High CPU usage on Windows when there is no internet connection available

visuve commented 1 month ago

What you expect to be happening.
- When there is no internet connection or no connection at all zerotier-one_x64.exe should just idle
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.
- Disconnect any ZeroTier connections
- Disconnect network cable
- Observe high CPU usage
Any relevant console output or screenshots.
- Can provide if needed
What operating system and ZeroTier version. Please try the latest ZeroTier release.
- Windows Server 2022 Datacenter 21H2
- Zerotier 1.14.0

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?

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.
