Connection stalled with long sync queue but no network activity

I’ve noticed that one of my devices has basically stopped syncing in the last few days. The GUI appears normal, but in reality, synchronisation seems to have stalled.

Download and upload rates stay at 0, and on the other device, there is a long queue of folders waiting to sync.

I’m attaching a support bundle from the “stalled” device below:

Syncthing version is v2.0.0-rc14 (386, compiled from https://github.com/tomasz1986/syncthing/tree/tomasz86/releases/tomasz86-v2.0.0-rc.14) running on Windows x86. Also, this seems to have started a few days after I began syncing a new folder sized at about 100 GB (with ignore patterns, as the folder itself is sized at 2.5 TB). As seen in the screenshot, the folder stopped downloading new files with about 46 GB still left.

I’d be very grateful if you could have a look at the attached files and let me know if there is anything obvious in there.

Anything in the logs?

Nothing special there, but the log file seemed to also be updated slowly, and not continuously, but in bursts.

However, I left the whole thing alone and overnight it actually came back to life and synced additional 10 GBs or so. I guess I just need more patience :sweat_smile::sweat_smile:.

Normally, it’s not that slow, however the newly added folder of 100 GB itself is located on very slow storage (in contrary to the other folders and the database), so maybe this is the reason for the slowness.
