Unable to broadcast sweep tx #2527
Description
Background
Lnd is crashing and restarting (because docker is set to restart). This user thinks he may have force closed a channel at the time this error started. There may have been some dust in the channel at that time.
Your environment
- lncli version 0.5.1-beta commit=v0.5.1-beta
- Linux lnd 4.14.70-v7+ Fixing some README typos #2 SMP Wed Sep 19 07:49:26 UTC 2018 armv7l Linux
- bitcoind: 0.17.0
- bitcoind and lnd are running in docker containers on a raspberry pi 3b+
Steps to reproduce
Unsure how to reproduce on other devices, but lnd logs on warn level produce the following snippet. We can turn up logging if that is helpful. I can also include the omitted txIn/txOut data if that helps.

Expected behaviour
Lnd should boot up normally and not crash.
Actual behaviour
Lnd fails to start and reboots because docker is set to restart automatically.
