Random crashes of daemon

Posted: Wed Dec 02, 2015 1:13 pm

Im running the latest version and have been plagued with crashes almost on a daily basis. This also affected me on previous version and I tried setting it up in supervisor to restart it when crashing but figured finding out the reason for the crashes is better.

Deluge version 1.3.12
libtorrent: 0.15.10.0
Raspbian 7
Label plugin
I think I used Deluge Team PPA or github for installing

The crash happens automatically when Im not using the software but just letting it run. It seems to be related to downloading, meaning when Im not downloading anything it is not as privy to crashing. It is not 100% always crashing when downloading however.

One crash log I saved show:
Unhandled error in Deferred:

log.debug("%s: %s", alert_type, alert.message())

Ill add more crash logs next time it dies on me.

ran it without daemon mode to see what message it would crash with. It gave me:

"pure virtual method called
terminate called without an active exception
Aborted"

nothing in log about crashing. It is running in info-mode now, switching to debug and starting over.

I don't know what the exact issue is but it's clearly a libtorrent problem. libtorrent 0.15 is unsupported now so you really need to be using the latest version anyway. It's not the latest version but you could try 0.16.18 from wheezy-backports: https://packages.debian.org/search?keyw ... -rasterbar

The only other option is to build libtorrent from source which can take a long time on an RPi unless you try cross-compiling on a desktop machine.

I saw your post in IRC, did you update python-libtorrent as well?

Yeah everything should be updated to the latest versions now. Built using instructions here http://dev.deluge-torrent.org/wiki/Building/libtorrent and everything went fine.
Running deluge 1.3.12
libtorrent 1.0.7.0

Still having crashes quite frequently, latest one when running not as daemon (only way to get any info at all as to why it crashes) says:
terminate called after throwing an instance of 'boost::bad_weak_ptr'
what(): tr1::bad_weak_ptr
Aborted

But mostly it just says segmentation fault.

Did you run `thread apply all backtrace` in gdb to get the full backtrace? Please report these findings to libtorrent: https://github.com/arvidn/libtorrent/issues
