Description Birjukov Dmitrij Aleksandrovich 2011-11-14 20:20:07 UTC
Application: ktorrent (4.1.2)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.4
Operating System: Linux 2.6.35.14-103.fc14.i686.PAE i686
Distribution: "Fedora release 14 (Laughlin)"

-- Information about the crash:
- What I was doing when the application crashed:
Before the failure was put about that "too much open files" and a torrent-Uploads a suspension (each time a different distribution). After some time, an error message appears. I apologize for my English. English is not my native language.

-- Backtrace:
Application: KTorrent (ktorrent), signal: Aborted
