I struggle because tor v0.4.8.1 on Debian trixie seems to consume quite some memory on startup. Few issues/questions:
- On startup it reports there is a bug
connection_edge.c:1086(see log below). This is new in comparison to v0.4.8.16 (bullseye) which was starting OK with same config without issues. - Sometimes tor crashes (see dump below)
- I wonder if ~380MB for lzma is really necessary? Can lzma be disabled (or configured to use less memory)?
Many thanks in advance!
