I ran a relay using Ubuntu with very few issues however I decide to add an additional relay and decided to use FreeBSD. They will only run for around 18 hours and then they shut down. I have adjust the torrc file every way I know how and increased the Max vnodes thinking this may have been my issue. I can post the sysrc and torrc if needed. Anyone that might help me figure this out I would be grateful otherwise I am going to reluctantly move them both back to Ubuntu. > > Emerald Onion runs over twenty Tor exit nodes on HardenedBSD 12 and > > 13.

Memory management is indeed different in HardenedBSD than in FreeBSD. HardenedBSD implemented a clean-room version of grsecurity's PaX ASLR. FreeBSD's version of ASLR, more appropriately called ASR, has known issues. HardenedBSD's does not.
