[tor-relays] [warn] Problem bootstrapping. Stuck at 10%: Finishing handshake with directory server.

[Martin Ekendahl]

This morning I rebooted my relay after some patching. I was running 2.6.7
on Ubuntu 14.04.2 LTS from. The server is always a bit slow rebooting but
when it came back up always check the Tor relay and now I see an excessive
amount of these errors:

May 29 12:20:36.000 [warn] Problem bootstrapping. Stuck at 10%: Finishing

I still see about 7000 inbound connections and 3000 outbound, I'm not sure
what my connection average is, but the current bandwidth being used is
below average (from the reboot).

There have been a couple DDOS alerts from my ISP the past couple days,
something I never used to get. I can confirm via my dashboard nothing has
been mitigated so I assume no filtering is going on, and traffic is still
coming and going, but for some reason there are a lot of connections not
being made it appears from the logs, and these only started appearing after
I restarted my server/relay. Any ideas what would be causing all these
issues?
