问题描述 报过两次connection reset by peer redis ，后面两次同步报EOF，不知道为什么？这里贴出配置信息

type = "sync"

[source]
version = 5.0 # redis version, such as 2.8, 4.0, 5.0, 6.0, 6.2, 7.0, ...
address = "xxxx:6379"
username = "" # keep empty if not using ACL
password = "" # keep empty if no authentication is required
tls = false
elasticache_psync = "" # using when source is ElastiCache. ref: https://github.com/alibaba/RedisShake/issues/373
[target]
type = "standalone" # "standalone" or "cluster"
version = 6.2 # redis version, such as 2.8, 4.0, 5.0, 6.0, 6.2, 7.0, ...
address = "xxxx:6379"
username = "" # keep empty if not using ACL
password = "" # keep empty if no authentication is required
tls = false
[advanced]
dir = "data"
ncpu = 4
pprof_port = 0
metrics_port = 0
log_file = "redis-shake.log"
log_level = "debug" # debug, info or warn
log_interval = 3 # in seconds
rdb_restore_command_behavior = "rewrite" # panic, rewrite or skip
pipeline_count_limit = 1024
#此处开始报错，我改了7000_000_000，仍然报错
target_redis_client_max_querybuf_len = 7000_000_000
target_redis_proto_max_bulk_len = 512_000_000

“scheduled to be closed ASAP for overcoming of output buffer limits” 源端断开的连接，网上搜一下这个报错，有很多原理解释。

[IJustOne]

config set client-output-buffer-limit "slave 0 0 0" 源redis设置这个，可以解决。又遇到 write: connection reset by peer；还在继续找问题

[suxb201]

不要改 target_redis_client_max_querybuf_len

[IJustOne]

改回原始了，仍然报写入连接失败，换方案了

[suxb201]

@IJustOne 请问新方案用什么做的？

@IJustOne 老哥 这个问题怎么解决的呀 tks
