From dbd2535f42301ce630a90631b47aa656d9a83d32 Mon Sep 17 00:00:00 2001 From: hashmap Date: Sun, 30 Jun 2019 22:26:17 +0200 Subject: [PATCH] Increase peer's send buffer (#2931) (#2934) When we send a txhashet archive a peer's thread is busy with sending it and can't send other messages, eg pings. If the network connection is slow buffer capacity 10 may be not enough, hence the peer's drop.
