Subnet router log spam

I’m running the Tailscale subnet router as a service on my hosting provider (
It works fine, but the router outputs a log line with just a bunch of equal signs every 5 seconds:


Is there a way to prevent this or at least reduce the frequency? I guess it does this as a “keepalive” of sorts to show the process is still running, but it’s not particularly useful and just makes it more difficult to access actual logs.

I don’t recognize that as part of our logging. Our logs are verbose, but don’t use that as any type of spacer/keepalive/etc that I’m aware of.

Yeah, sorry, it turns out that this line was emitted by a wrapper script around Tailscale provided by our hosting provider. We’ve fixed it now.
