[warn] Error binding network socket: Address already in use

[D-503]

This is interesting. The message itself is saying that some other
application is already using this port, thus tor cannot bind to it.
In most cases you are trying to start tor but it's already running. You
can verify this with:
 $ pgrep tor
or
 # netstat -tulpen|grep tor
or
 # lsof -i :9050

But what I'm asking myself now: why is this just a warning- and no
error-message? This should make tor not to start which should be an
error and no warning or shouldn't it?

greetings
