Channels to online peers becoming inactive. Disconnect/reconnect brings them back online

[mrfelton]

Background

We have a number of channels that keep flipping to an offline status even though I know for a fact that the peer is online.

For example, I could have 2 channels open to some node with one of them showing as online and the other showing as offline at the same time. The peer clearly can't be both online and offline at the same time. Also, I have channels to the same peer from another node and those channels are also showing as online.

If I issue lncli disconnect and then lncli connect the offline channel will start showing as online again (sometimes just lncli disconnect is enough without the subsequent connect call)

Your environment

• version of lnd: 0.11.1-beta
• which operating system (uname -a on *Nix): alpine
• version of btcd, bitcoind, or other backend: bitcoind
• any other relevant environment details

Steps to reproduce

Not sure. Seems to happen randomly but relatively frequently (most days)

Expected behaviour

Channel should remain active continuously unless the peer is actually offline.

Actual behaviour

Channel randomly gos into offline state even though the channel peer is online.
