Hi, I have just setup a tor-relay and I am wondering if the resource requirements are still current: "A non-exit relay faster than 40MBit/s should have at least 1 GB of RAM."[1] My relay is sitting at ~2.77G currently. I set the option: MaxMemInQueues 6GB Just wondering if this is any cause for concern? I realize the utilization is less than the limit but I just don't remember relays I have run in the past using this much memory.

Yes, I still believe that you can run a relay if you have just 1 GB of RAM. (this is a lower boundary)
My relay is sitting at ~2.77G currently.
assuming we talk about: https://metrics.torproject.org/rs.html#details/8BB171D82DDEC2CC751C5B63BA543... I consider that a lot of memory for a relay added on 2018-02-15 and not being guard yet. You are currently running version 0.3.1.9 which is lacking the latest denial of service mitigations, it will get a lot better with the upcoming stable releases or if you upgrade to tor 0.3.3.2-alpha or newer. -- https://mastodon.social/@nusenu twitter: @nusenu_

I upgraded and replaced musl's malloc with tcmalloc. Now memory feels stable (currently at ~1.3G). I also ran with heap profiling enabled for a day. Nothing interesting there. I do see messages printed: DoS mitigation since startup: 1632 circuits rejected, 6 marked addresses. 557 connections closed. 900 single hop clients refused. Whether it was an attack or just my unfamiliarity with musl I guess we will never know...
