## Issue Addressed NA ## Proposed Changes This PR expands the time that entries exist in the gossip-sub duplicate cache. Recent investigations found that this cache is one slot (12s) shorter than the period for which an attestation is permitted to propagate on the gossip network. Before #2540, this was causing peers to be unnecessarily down-scored for sending old attestations. Although that issue has been fixed, the duplicate cache time is increased here to avoid such messages from getting any further up the networking stack then required. ## Additional Info NA
