[bug]: Sats remain pending

[MichaelAntonFischer]

Background

Several UTXOs stuck.

Your environment

• version of lnd 0.16.4
• which operating system (uname -a on *Nix) Debian 11
• version of btcd, bitcoind, or other backend bitcoind/neutrino
• any other relevant environment details

Steps to reproduce

I have previously had the issue that on my neutrino LND node, some sats would be stuck after channel closes. Normally briefly switching back to bitcoind backend would resolve the issue, but now I have quite a lot of sats stuck for weeks even though I have been back to bitcoind for 5 days since.

[bitromortac]

Do those UTXOs belong to any sweeps lncli wallet listsweeps --verbose or can you link them to your pending closes?

[MichaelAntonFischer]

Yes, but to be more specific the sats are shown as pending the channels are shown as closed.

[bitromortac]

The sweep you posted is another instance of a foreign anchor sweep interfering with the internal sweep (see this outpoint https://mempool.space/tx/8b65fc87db7bd6f23756944261769352739f791495df0a23c877315ec4b1e3f4#vout=0). The external sweep is still unconfirmed (https://mempool.space/tx/443bdac052fc92b94137c3cb0dbb140cded7acb7cc307348feff84fb42d6f428).

[MichaelAntonFischer]

Hi,

looks like the transaction was never confirmed and is gone from the mempool. Is there anyway to trigger LND to do the sweep again?

[aeonBTC]

I am having the same issue

[Opago-Pay]

I used an online tool to rebroadcast and fee bump the transaction.

Do you have pending channels? Could you show the outputs of interest?
