Many thanks Peter for that.

No worries, I won't play with CPU or RAM, it's just all the
transaction-relay
and mempool logic that one can interfere with. I'll make you whole of the
$2400
if the LND node goes down too hard, though I'm just looking for a node
running
on mainnet, for a pinning the attacker has two open to channels and
re-balance
the liquidity at its advantage a bit. I'll provide the liquidity by myself.

If you have an on-chain donation address on the OTS website (?), I'll make a
$100 donation now, it's a nice tool. And for the justice transaction...well
for some scenarios you can use the latest valid commitment state to pin no
risk
of being slashed by a justice transaction.

Best,
Antoine
