Tor relay dying in FreeBSD
Hello, I just installed a new relay in a fresh FreeBSD installation. The relay starts fine, except for a warning that I don't understand. Then it dies all of a sudden. The time before it dies is different every time. I have googled for the warnings but could not find anything. Does anyone here know what is going on? Tor 0.3.1.4-alpha (git-fab91a290ded3e74) running on FreeBSD with Libevent 2.1.8-stable, OpenSSL 1.0.2j-freebsd, Zlib 1.2.8, Liblzma N/A, and Libzstd N/A. Jul 12 23:44:24.672 [warn] You appear to lack permissions to change memory limits. Are you root? Jul 12 23:44:24.672 [warn] Unable to raise RLIMIT_MEMLOCK: Operation not permitted .... Jul 12 23:44:29.000 [notice] Self-testing indicates your ORPort is reachable from the outside. Excellent. Jul 12 23:44:30.000 [err] Out of memory on realloc(). Dying. It's the tor-devel version installed from ports. Thanks in advance.

Thanks for pointing me in the right direction! The 128M for daemon processes was too low. I added this in /etc/login.conf: _tor:\ :memorylocked=unlimited:\ :tc=default: The warnings are gone and the process is not dying anymore. Maybe I should tinker and find a value better than unlimited... ________________________________________ From: tor-relays <tor-relays-bounces@lists.torproject.org> on behalf of Alexander Nasonov <alnsn@yandex.ru> Sent: 13 July 2017 00:46 To: tor-relays@lists.torproject.org Subject: Re: [tor-relays] Tor relay dying in FreeBSD Farid Joubbi wrote:

On a large (300 Mbps) exit on Linux, 1-1.5GB RAM is reasonable. On a non-exit or smaller exit relay, you may be able to get away with 500-750 MB. But it's best to allow more so your relay doesn't die the moment it gets a load spike.
