Comment:

 Most likely the ongoing DDoS on the network is affecting your relay. The
 tor-relays@ mailing list archive has many discussions going on about this.
 I'm not very familiar with `mbuf` in FreeBSD but if this is related to a
 connection limit, you can bump it higher.

 The other option is to set `MaxMemInQueues` (man tor) to a reasonable
 limit of RAM you want your relay to use and once that limit is reached,
 Tor will triggers its OOM to remove bytes from memory and thus putting
 less pressure on the network.

 Appart from that, we are currently working on fixes to improve "tor" to
 deal better with this DDoS. Please, update the tickets with any more
 information you can gather on this.

 Thanks!
