[BUG] Intermittent SQLIte3 connection errors prevent syncing until app is restarted

See original GitHub issue

Summary

The Augur app sometimes gets stuck on SQLite3 connection errors, which persist and block any syncing progress until the app is restarted. Everything seems to work fine after the restart.

Steps to reproduce

Not sure, it seems to happen more or less randomly. I have seen it occur after the app has been up and syncing normally for a while, as well as shortly after starting and before fully syncing in the first place.

It’s happened for me twice in the last few days with “Local Light Node (experimental).” I think I’ve also seen it in the past using Alchemy and even gethnode (back when that worked), but can’t prove it yet.

Expected behavior

No errors, or at least no need to restart the app manually.

@ndorf I don’t believe there were any recent changes that would have fixed it, so we’ll investigate it more. If you do see it in 1.9.1 or 1.9.2, please let us know just to confirm.

This might have been fixed by the recent changes made to Augur Node, but it will need more investigation by one of the devs to confirm.
