rtorrent crashes periodically on debian 8

[2600box]

libtorrent-0.13.6 rtorrent-0.9.6.tar.gz

currently only have 350 torrents. no new torrents added recently. rtorrent crashes at random after hours of operation.

this causes a rehash on restart of course! which is painfully slow and annoying.

I just built from the feature branch and I still have these crashes on debian.

I thought it might be related to my config. Here is what I used for the most recent crash.

I'm also having this issue on Debian 8 with the same version of libtorrent and rtorrent. My config is set to log critical, but my logs are empty.

[Neonlinx]

I have this problem on Deb 10.... I tried all the solutions proposed in other threads; but without success. The problem comes back after a while. And honestly, thousands of users have had this same problem....for years....and sadly, at this point, I don't think it will ever be fixed. Indeed, sincerely with great sadness, it seems to me that this project is now destined to end.
