Comment (by torkit):

 I can also confirm the problem on Ubuntu 18.04, installed from
 deb.torproject.org:

 `Tor 0.3.4.8 (git-5da0e95e4871a0a1) running on Linux with Libevent
 2.1.8-stable, OpenSSL 1.1.0g, Zlib 1.2.11, Liblzma 5.2.2, and Libzstd
 1.3.3.`

 System is on auto-update, problems started on Oct 5th, 10pm UTC. There do
 not seem to have been any updates during that time period.

 Leak fills up memory roughly every 4h and restarts the process. The relay
 is not an exit node, but a fallback-directory. I'm happy to help
 investigating.

 Please contact me at the provided relay address:
