XRP Ledger Hotfix Addresses Validator-Manifest Flood

The XRP Ledger has released a hotfix to address a validator-manifest flood that strained its peer-to-peer infrastructure on July 31. The flood caused individual servers to face abnormal data pressure, but consensus remained active and ledgers continued to close normally.

Version 3.2.1 of xrpld introduces limits designed to prevent unknown validator data from consuming excessive memory, bandwidth, storage, and processing capacity. These changes apply controls at four points where oversized or repeated manifest traffic could burden a node.

The hotfix rejects individual manifests that exceed the expected encoded size before decoding begins, discards incoming batches containing excessive numbers of untrusted manifests, limits bulk manifest greetings exchanged when nodes establish new peer connections, and restricts storage of untrusted manifests to 100 entries per node.
