Noticed a bunch of probes getting stuck on them today. That makes sense.
@benthecarman has expressed this before but the hodl invoice APIs seem to have a bit of a scalability concern, if it still requires subscribing to each payment hash individually instead of a single API call for subscribing to all invoices like normal.
Boostraping liquidity to a new node and doing all those channel closes with the risk of all those in flight hodl htlc's... I do not envy them but I do not see another option. Can't wait weeks to months for LND to fix issues like this. Hopefully they don't run into another unresolved bug causing multi-thousand-dollar force closes while they go through this.
