predixy will be close with status 4 EventError

一条完整日志如下，在predixy中出现了很多条，且都是业务有问题的时间范围内出现的 2023-07-19 08:06:32.795441 E Handler.cpp:437 h 0 s r-xxx.redis.rds.aliyuncs.com:6379 84 will be close with status 4 EventError

手动连接predixy，使用get/set命令报错（与业务抛出的错误一致） 127.0.0.1:6379> set key111 value (error) ERR no server connection avaliable

重启predixy后恢复

我的predixy配置如下，后端是阿里云的redis ` cat /usr/local/predixy/predixy.conf Name auth-predixy Bind 0.0.0.0:6379 WorkerThreads 2 MaxMemory 1G ClientTimeout 300 BufSize 8192 Log /var/log/predixy.log LogRotate 1d LogVerbSample 0 LogDebugSample 0 LogInfoSample 10000 LogNoticeSample 1 LogWarnSample 1 LogErrorSample 1

`

想请教下问题的原因，我猜测可能是阿里云的域名对应ip变了，但predixy可能没有识别出来？
