Lightning channel in regtest closed due to update_fee of zero being out of range

0
187


I am running a testbed of c-lightning clients running inside Docker containers connected to a bitcoind back-end. I keep running into problems with channels closing because the update_fee is out of range. The update_fee is always zero, which I don’t understand.

I thought the ignore-fee-limits option was meant to keep nodes from closing channels due to update_fee being out of range, but if I run all nodes with this option, nothing changes.

Then I thought it might have to do with estimatesmartfee not returning an estimate because of insufficient data, but even if I generate a bunch of transactions to have enough data so that bitcoin-cli estimatesmartfee 2 does not return an error, this error still happens.

The thing is, I am trying to route a set of payments over a fixed route, and after a few tries, the channel suddenly closes down. These are the combined logs of the nodes:

I am aware that there are WIRE_INCORRECT_OR_UNKNOWN_PAYMENT_DETAILS and WIRE_TEMPORARY_CHANNEL_FAILURE errors. These are to be expected because of the specifics of the payments, so I don’t think the problem lies there.
