[I] seata-server报错：Decode frame error, cause: Adjusted frame length exceeds 8388608: 539959368 - discarded [incubator-seata]
wxrqforever opened a new issue, #7013:

Hi
一、部署背景和报错信息：
我们刚在线上部署了base nacos的seata-server多个集群，比如广州一区和广州二区，但是实际上只有广州一区是对外提供服务的(事务分组配置的广州一区)，上线后我们观察广州和南京的seata-server日志都有偶发的如下报错信息(一天两到三次)：
以下涉及ip的部分用变量替换了：
以下日志中的“某容器IP”为同一ip，但是并不是和server交互的客户端ip
广州一区（对外提供服务）报错日志:
```

广州二区（不对外提供服务）报错日志:

```
二、定位
在相关历史issues检索，初步怀疑是“某未知容器IP”访问了rpc端口8091，因此我们改了广州二区的rpc端口为9527，但是仍然会收到以上的报错信息(上吗的报错信息就是在修改端口后，只修改广州二区，一区不变)，此外我们咨询了相关服务这个“某未知容器IP”是节点ip，不存在会访问主机任意端口的行为。
因此想请教下以上日志信息是否有其他可能性导致？
三、版本信息
seata-server:1.8.0
seata-spring-boot-starter:2.1.0
spring-cloud-starter-alibaba-seata:2021.0.6.1
以上期待您的解答🌹

大概率就是你说的有其他地方在探测端口导致的，对事务无影响，可忽略
The high probability is that there are other places probing the port as you said, which has no effect on the transaction and can be ignored.
