What is causing deluged to crash?

Deluged frequently crashes, sometimes multiple times within a few minutes. It's not really reproducable on demand, but I seem to notice it more when a torrent is actively downloading, especially if the torrent is well seeded and moving quickly (or it might just be that I only pay attention to it when I'm actively using it).

I have the log level set to Error, and after each crash I find this in the log:

Code: Select all

14:01:41 ERROR    config:387 No JSON object could be decoded
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/deluge/config.py", line 385, in load
    self.__config.update(json.loads(data[start:end]))
  File "/usr/lib/python2.7/json/__init__.py", line 326, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python2.7/json/decoder.py", line 384, in raw_decode
    raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded
Can anyone tell me what caused that? Or does anyone have suggestions on how I might get a more useful error? Thanks in advance.

Are you sure it is deluge-web that is crashing and not deluged?

That error is a problem with a config file being loaded.

Thanks for responding. Yeah, deluged is crashing, not deluge-web. Sorry about the confusion.

If there is a problem with a config file, which file and which part of the file is causing deluged to crash? Is there any kind of syntax checker for the config file?

deluged crashing is known and many many threads in the forum about it... update to libtorrent 0.16 (see this PPA)... the config error is unrelated but you could try a fresh config to see if it resolves that

also update Deluge to 1.3.6

Update libtorrent is a great solution!

At this point i'm done researching it by myself. Random crashes persistence through years of deluge existence is killing me and unfortunately i would better refuse using p2p at all, once and forever, rather than keep digging in this ****, especially python ****... <- Since 1.3.11 works with this config, but starts ignoring port ranges.
