fedora rpm doesn't set ulimit -n, so you can't run a fast relay
If you run a fast relay, you will end up using more than the default 1024 file descriptors. Currently we point people who run relays to https://www.torproject.org/docs/tor-doc-relay.html.en and hope they read through to item #14 (closed).
Debian, on the other hand, has a clause in the init script: https://gitweb.torproject.org/debian/tor.git/blob_plain/HEAD:/debian/tor.init that sets MAX_FILEDESCRIPTORS based on how many file descriptors are available on the machine, before it launches the Tor process.
