POA：Geth 節點（礦工）在 3-4 小時後自動停止，導致主節點暫停並尋找對等節點

我在不同的機器上設置了 2 個帶有 POA 的 Geth 節點。啟動bootnode和啟動Geth節點後，同步良好，交替開始挖礦。如果我手動停止一個節點，其他節點會繼續尋找對等節點。如果我重新啟動兩個節點，它們會再次開始正常工作。但是 3-4 小時後，當他們暫停礦工到“將記憶體狀態寫入磁碟”和“保持乾淨的 trie 記憶體”時，Node2 嘗試重新啟動探勘並出現以下錯誤：

Please note that in the error message `Served miner_start conn=84.147.159.252:62347` This is an unknown IP address so I think the miner tries to connect with an unknown node and is failing to find Etherbase account on that node?

我能夠通過在 Geth 命令中添加--nodiscover和來解決這個問題，--netrestrict <CIDR>這有助於防止未知節點與我的節點連接。

對於即使在實施上述建議後仍面臨類似問題的使用者，請嘗試在 Geth Command 中減少 RPC-API。只使用必要的，因為那裡有許多機器人可能會嘗試連接和更改您的 etherbase 帳戶、進行交易等。
