Rutorrent immediately crashes rtorrent.

I am using rtorrent and rutorrent on a NAS. It was working fine, but for some reason the rtorrent's UP/DOWN limits weren't shown in Rutorrent. So I opened the rtorrent screen and ^q then started rtorrent with the init.d script.

Now, whenever I open rutorrent it immediately crashes rtorrent. The rtorrent logfile is completely blank.

I am running rutorrent over lighttpd. Can anyone help me figure out this issue?




here are some files of interest.

Start rtorrent from the command line and start rutorrent. What error message are you seeing?

I couldn't reproduce that.

Delete all plugins.
Delete all ruTorrent user settings (share folder).
Re-install ruTorrent.
Try a new minimal .rtorrent.rc file with just the required options (eg. watch dir, session dir).

BTW, there's no stop_on_ratio function, so your schedule = ratio,30,60,stop_on_ratio=200 always gives an error message.

I have had the same problem. I only recompile whole rtorrent program (libtorrent, xmlrpc and rtorrent) and it works fine.

good luck

Something bad with xmlrpc-c library. For example, you have two copy of this library - rtorrent was compiled with first, but load second. Say
ldd rtorrent
and check - what it load at runtime.

This happens on debian based linux a lot. debian comes with some xmlrpc.

To prevent this issue, i typically specify the path for xmlrpc-c-config via the ./configure script
