为何pos节点总是无法完成同步？

#1

我的个人节点总是同步到接近完成，然后就如下：
2023-07-09T10:17:26.954591554+08:00 INFO IO Worker #3 cfxcore::syn - Catch-up mode: true, latest epoch: 74818103 missing_bodies: 0
2023-07-09T10:17:27.956456503+08:00 WARN IO Worker #3 cfxcore::syn - current sync candidate becomes inactive: (status = about to request a candidate state, pending_peers: 0, manifest: None, chunks: Some((download = 4430/0/16239, active_peers: 0)))

#2

还有一个现象，如果持续报以下错误，同步就还在进行，如果不报错，同步反而停滞了。

我是被恶意消息攻击了么？
我的conflux版本是conflux-rust/v2.2.4-179a5bc-20230505/x86_64-linux-gnu/rustc1.68.0

#4

我搜了一遍pos账户，发现向我的节点发错误消息的节点peer=0xc22a…7efb并没有出现在confluxscan的pos accounts中。
