Description Thomas Janssen 2008-07-19 08:21:09 UTC
Description of problem:
rtorrent or libtorrent crashes after a few minutes (konsole) or like 30 minutes
(gnome-terminal) runtime. This is a installation from a kde4-livecd of Fedora 9.
The system is uptodate until SatJul19. I will add a screenshot of it, because i
cant describe how it looks.

Version-Release number of selected component (if applicable):
Konsole Version 2.0 on KDE 4.0.5

How reproducible:
Just start rtorrent and let it run for a while

Steps to Reproduce:
1. start rtorrent with some torrents in
2. wait (her it needs just up to 30 minutes)
Actual results:
Like in the screenshot, crashing rtorrent

Expected results:
A rtorrent that works like before in F8, rock solid.

Additional info:
I will see if i can strace it.

I hope it is helpful. If you need more or the output of other commands let me know.

Comment 4 Nikolay Vladimirov 2008-07-26 20:47:18 UTC
what version of libcurl are you using ? 

Comment 5 Nikolay Vladimirov 2008-07-26 21:01:15 UTC
I'm having the same crash. I noticed that downgrading curl to 7.17.1 the crash
doesn't happen. Not sure about this. I may be just a coincidence. Can you try this? 

Comment 6 Thomas Janssen 2008-07-28 19:59:50 UTC
Well.. Interesting is, i tested rtorrent on another Box
(libcurl-7.18.2-1.fc9.i386) and without my old rtorrent.rc with just 1 File
(community-respin) and it runs for hours now.
It seems it is related to the old rtorrent.rc (i`ve done copy/paste from F8 to
F9) or if there are to many torrents the same time (about 40-50).

I cant test it again on the Box that fails, because there is no more Fedora on
it. There was to much trouble on this Laptop with Fedora, so i changed to
another Linux Distro.
But rtorrent runs on the Desktopsystem with F9, no rtorrent.rc and just 1 torrent.

Comment 7 Michael Schwendt 2008-07-28 20:20:53 UTC
What does it look like if you get a full backtrace?

Comment 8 Nikolay Vladimirov 2008-07-29 08:58:11 UTC
Ah, I'm running rtorrent with about 50 torrents for 2 days now with no problem.
Latest rawhide. I guess this can be closed since no one  can reproduce it and
provide a backtrace.

Comment 9 Nikolay Vladimirov 2008-12-23 17:53:36 UTC
Still no problem with fedora 10: 

I'm closing this. No need to be open since no one has complained for 4 months.

Comment 10 Shawn Baker 2009-04-11 20:39:59 UTC
I'm getting this issue on fully-updated Fedora 10. rtorrent will run for between 30 minutes and a few hours before crashing with SIGABRT. Here's the backtrace made by following the directions in the aforementioned link:

Comment 11 Michael Schwendt 2009-04-12 06:25:43 UTC
To Shawn Baker:

This ticket is a closed one. Please open a new one. Your backtrace would be more detailed if you installed "nss-debuginfo" and "curl-debuginfo" e.g. by running "debuginfo-install -y nss curl", because the backtrace is deep into NSS.
