pub const MAX_PENDING_REQUESTS: usize = 64;Expand description
The most unanswered requests this node holds at once (D72).
The endpoint that fills this table is the only one on the node an unauthenticated caller can use to write to disk, so it needs a ceiling that is not “the disk”. Sixty-four is a queue a person can actually read; past that the honest answer to the sixty-fifth stranger is that the operator is not keeping up, which is what the refusal says.
