[tor-relays] stable flag

My relay seems to gain and lose the stable flag every day for the last several days. It's been up more than a week. Is this normal? I don't recall seeing this on a previous hosting provider and I suspect there is something going on with the network.

I'm thinking of setting the log level to info or debug to try to figure out what is going on. Is that a good idea? Is it likely to be informative?

Thanks
