Error: unexpected end of file in bencoded string

[UglyBob]

I'm having serious trouble with Deluge and REALLY need your help. Maybe for a month or two my torrents started to end up in queued state after completion with the tracker status saying "Error: unexpected end of file in bencoded string". This happens usually after a little while of seeding. I tried everything to solve it, reinstalling Deluge, upgrading, finally I even deleted my whole seed folder and created a new one. This solved the problem for a while, but now it has come back. Someone said that I might have a broken disk or RAM, but I have run memory and disk test and couldn't find anything....

I'm running Deluge headless on a small Arch linux machine with an external USB disk as the seed disk.

My versions are:
Client: 1.3.7
Server: 1.3.13
libtorrent: 1.1.1.0

Extremely greatful for any hints on how to investigate this, getting a little bit desperate...

No ideas? Any log I can check? Any debug options to try? Anything is helpful...

Similar issue. Memory is healthy too. The error appears but the torrent will continue to download or seed. One newly added torrent had this problem while 4 old torrents started showing this error at the same time. All torrents were added from a torrent file and not a magnet.

I don't understand the nature of it, is the torrents.state file becoming corrupted somehow?

I have other problems with the state folder that you can see in my other post.

Deluge 1.3.15
