Using CVS from 01/04/06. Two problems here.

Well I got this error for some torrents, "Cannot open index file (...): Too many open files", so I set my open file limit higher with ulimit. I guess this is the proper way to fix this (?) and I haven't had the error again, yet. Maybe someone can clarify this? I had a size of 1024 before, but I have no idea how this limit could possibly have been reached unless ktorrent keeps all files open in torrents EVEN those that are not checked for download (can somebody verify this..??).

However, in the meantime, when I did get this error, then sometimes in the same session, when I tried to restart the download that had the error, ktorrent would crash with this:

I can try messing around with my open files limit. To see if I can reproduce it.

KT keeps all files open, even the ones not selected for downloading, because we might need to write to them anyway (a torrent is divided into chunks, chunks do not follow file borders, so a chunk can lie in 2 or more files)
