Comment (by r1610091651@…):
Some additional info.
I've downgraded to 3.3.7 this weekend, and relay is stable again. Noticed
following though:

week.png?dl=1)]]
After upgrade from 3.3.7 -> 3.4.8 I've noticed a drop in throughput with
similar #connections & weight. Now with downgrade done, i see increase in
throughput again.
Could it be that somewhere between 3.3.7 -> 3.4.8 stream compression was
added? That could explain the drop in network usage, and if resources used
for that compression aren't released properly also the memory leak, all
with similar connection count & weight..
Regards
