Codis-proxy Session closed by error: EOF

[Dingyang]

背景：使用redis-migrate-tool向codis+pika的架构同步数据，同步模式为全量+增量，源端为redis cluster 4.0，目标端为coids-proxy地址，目前可以正常同步，但是到增量阶段大概8小时左右，就会出现session close的错误，导致同步进程Crash，redis-migrate-tool日志没有任何报错，在codis proxy日志只可以看到：

2023/05/25 15:51:16 session.go:83: [INFO] session [0xc012833600] create: {"ops":0,"create":1685001076,"remote":"192.168.3.26:39470"}
2023/05/25 22:53:10 session.go:90: [INFO] session [0xc012833600] closed: {"ops":136162772,"create":1685001076,"lastop":1685026390,"remote":"192.168.3.26:39470"}, error: EOF

codis配置文件为：

不知道是由于什么问题导致的同步进程中断，希望大家可以给予提示和帮助，谢谢。
