 Tor 0.2.2.34 on FreeBSD 8.2 currently use 2-3% of the CPU but still logs
 this:

 The relay is quite new and named fejk. It used 100% of one CPU core when
 it started to get a lot of traffic after some days. I have created a
 second tor process named fejk1 to share the usage over two cores. But the
 above message occurs now with only 1 Mbit/s of traffic an a low CPU usage.
 #4386 might experience the same problem but I see it logged more
 frequently. Any ideas?
