#27813: Tor 0.3.4.8 is leaking memory

Comment (by mem):
it happens also here (tor relay configured as non-exit)
It takes about 8 hours to eat up 4GB of memory, then it starts eating
swap, when it is done with swap it gets killed (oom-killer) and started
again by systemd.
it happens pretty reliably (every day since upgrading from 0.3.3.x)
only observed on Ubuntu 18.04 (not on Debian 9 or FreeBSD also running
0.3.4.8)
the system is also running nyx
I can not help debugging since I've no access to the affected box (just
saw the monitoring and logs)
> We really need somebody who can run Tor as a middle relay using tcmalloc
or a similar memory usage profiling tool. That would have the best chance
to tell us what accounts for the increased memory usage.
can you write down the steps to do so, so affected people can collect the
necessary information?
