I've recently started using rtorrent, and it's easily my favourite bittorrent
client. I was wondering whether you could shed any light on this error:
Caught exception: "core::DownloadStore::save(...) could not open file"
I get it while running one rtorrent instance using the session option which
works happily. I then want to open another instance (using the -s ""
parameter so as to disable the session store set in the rtorrent.rc), but I
get this error. I want the other instance so I can control the bandwidth
limiting for this torrent seperately. I also get the error if I do rtorrent
-s "" then add a torrent manually. rtorrent gets as far as populating the
torrent download directory. Am I doing something wrong? I have my
max_open_files set to 512, 128 seemed a little small given that one of the
torrents I'm running has >20000 files. I'm running rtorrent 0.3.6 on gentoo.
Thankyou for your help.
Below is an strace, no idea if it's any help:
