I'm also experiencing this, and I'm really disappointed that the error message doesn't contain *any* hint of what's failing.

Hi @tjjh89017 It appears the mmap storage in libtorrent 2.0 indeeds performs worse than the `pread`/`pwrite` in libtorrent 1.x. I've been working on an [alternative backend](https://github.com/arvidn/libtorrent/pull/7013) for 2.1 that uses...

the python callback requires that libtorrent locks the GIL, which is questional to begin with. This is probably the reason for the deadlock when using multiple threads. In your example,...

can you provide more details about the "crash"? is it an assertion failure? Is it a `SIGSEGV`? the stack trace you post is an exception being thrown because a file...

this will penalise peers that are close to completing the torrent, but that we see for the first time, right? Also, with this change, the comment above, with the ascii-art...
