5 years ago For channels that have a very small amount lingering like:
{
"channel": {
"remote_node_pub": "03a96577e4cf8cac96937f4bf2753f7bd71323af5563690c8ed39c4e058c66c6c7",

"capacity": "50000",
"local_balance": "579",
"remote_balance": "0"
},
"closing_txid": "15ea01435c9d6fc9433d581254c507e74a89a7b6c9572f048011996a94724517",
"limbo_balance": "579",
"maturity_height": 560282,
"blocks_til_maturity": -423,
"recovered_balance": "0",
"pending_htlcs": [
]
},We won't yet sweep those since we'll likely pay more in fees that we'll get from the output. This will change in the future though, in order to promote the wallet having a small UTXO footprint.
Many of those other channels for example:
{
"channel": {
"remote_node_pub": "02c12b5459cf107ee0440cae41902f1189db50fa003a077f3a6fbe6b5760218695",

]Haven't yet had their timelocks expire.
The final case in your report seems to be channels that have been closed with no coins on our side, but which are still showing up in pendingchannels (shows zero balance at time of close). Are you running a node with a txindex, and also can you provide logs with those txid's

Background
I am closing my first LND node which has gone through several updates to start a fresh node. So I'm closing all my channels (about 100 with around 2 BTC capacity) to get the funds out.
Most of the active channels were easy and they closed. The inactive channels I had to force close.
Your environment
Steps to reproduce
I also wrote some of this up here: https://www.zapread.com/Post/Detail/3784
I waited 48 hours after closing all channels, and then I went to send funds to my new node using --sweepall
I got the error that utxo were already spent, so I used the dropwtxn tool as described in https://github.com/lightningnetwork/lnd/issues/1494
I rescanned the wallet over the last several hours, and the ballance went from around 0.3 BTC remaining to about 0.05.
I look at pendingchannels:
Yes, there's a few recent transactions which I'm waiting to mature - it's the ones with 0 and negative blocks to maturity that I can't sweep.
Take the first one for example: The closing txn is confirmed a long time ago https://blockstream.info/tx/1fdf0393254efd7bdb937c339a01ece4f67e0f601f17681b9519abeefed5eb6d
It looks like it swept into https://blockstream.info/address/bc1qpwszjpd767a7d5he7l07wpdkhh92v4mkja9wxx
but, I can't see it in listchaintxns | grep bc1qpwszjpd767a7d5he7l07wpdkhh92v4mkja9wxx
Here is my log when starting up. You can see that LND tries to do a sweep, but it is not actually broadcast.
Expected behaviour
Channels should close and sweep into wallet
Actual behaviour
Funds stuck in limbo
