LTS branch leaks memory continuously under stress/attack, requires back-port of 0.3.2.8-rc fixes to remain viable
I am a fan of running LTS releases, however 0.2.9.14 leaks memory continuously on relays serving as HSDIR for an apparently popular onion service and while also under attack.
Daemon leaked 1GB in eight hours growing from 1.5GB VMRSS to 2.4GB VMRSS and was killed due to limited RAM.
To remain viable 0.2.9 branch requires backports of 0.3.2.8-rc memory fixes, otherwise must be deprecated.
Presently I am switching to 0.3.2.8-rc to see how the relay behaves the next time this happens. Lately high-volume onion services come its way shortly after the HSDIR flag is assigned.
