[rustyrussell]

We retry because this failure often means there's insufficient capacity, so we can try with less.

The assert fail shouldn't happen though...

[daywalker90]

These are my own channels, i should know their capacity.
The ones with 2471854x37x are all mine.

[daywalker90]

Also i dont see any capacity knowledge gained in the steps above, i see the same capacity for an errored channel in n and n+1

[Lagrang3]

It's weird that all of those local channels are failing. It shouldn't be for lack of liquidity. renepay always calls listpeerchannels at the moment of payment to fetch the exact spendable amount in local channels.

It looks that renepay is trying to send through that channel 2471854x37x5 as much flow as the spendable amount. It shouldn't be a problem, I tried that case in regtest.

[daywalker90]

on mainnet i sometimes do payments over a single channel and there i sometimes encounter this problem as well. I could only send (spendable_msat - X)msat (i usually use 1_000_000msat for X).

[rustyrussell]

OK, spendable is an approximation. Ofc if could be actually buggy, but also it assumes it we add a single HTLC. Adding more than that can reduce the amount (since we have to pay more fees). Could that be the case here?

No, but to be fair, renepay doesn't even believe it will work right?

sendpay flow groupid=1, partid=7, delivering=187457000msat, probability=0.000
...
# Update chan knowledge scid=2471854x37x7, dir=1: [187457878msat,187457878msat]
...
# sendpay flow groupid=1, partid=12, delivering=187457000msat, probability=0.000

If it really believes the range to be 187457878msat - 187457878msat, it should give probability=1.000 surely?

What about this:
