Memory limits for Tor process

[Vort]

From this topic: [tor-relays] relay memory leak?

The other option that can help with memory pressure usually is the
“MaxMemInQueues” (man 1 tor). Essentially, it tells “tor” when to start
running its “out of memory handler” (OOM). It is usually set around 75% of your total memory but you could reduce it and see if this helps.

I would although, in the current network conditions, really NOT put it below
2GB.

Selection of 75% of total memory is a strange decision.
Tor easily exceeds 1.33 (1 / 0.75) of MaxMemInQueues.
My record is 3.5 GiB working set with MaxMemInQueues 1 GB.
For selecting of the best value for MaxMemInQueues it is better to know at least approximate formula for maximum total memory consumption of Tor process.
