when you run multipath payment, each chunk that succeeds locks that capacity for some time until you figure out rest of the chunks. and since each chunk is tiny, the chance that all of them succeed on first try is actually quite large.

So you can DoS the network by spamming it with transactions that are set up to fail and lock up large sums of money?

Maybe you are right that I do not know enough about the Lightning network, because I was not aware there was a vulnerability that big and easy to exploit built into it.

well i'm glad you've conceded all the ground from "it's unsolvable comp sci problem" up until "but one can DoS the tiny payments by spamming". i've covered a mile, you're still fighting for inches, i think that's enough for me. cheers, i'm glad you learned a lot about lightning today!

p.s. i'm sure you can google about DoS attacks on lightning and how to deal with them yourself

No, it's still an unsolvable problem. But it seems a kludge has been added that makes the damage a tiny bit smaller, and also introduces a massive vulnerability, so I wouldn't exactly call that a win.
