根因分析

Redis 服务器的命令队列已达到最大容量（由 client-output-buffer-limit 控制），导致来自客户端的新命令被拒绝。

English

The Redis server's command queue has reached its maximum capacity (controlled by client-output-buffer-limit), causing new commands from the client to be rejected.

解决方案

  1. Increase the client output buffer limit for the relevant client type (e.g., normal) in redis.conf:
client-output-buffer-limit normal 0 0 0
Then restart Redis or send CONFIG SET command.
  2. Reduce the number of pipelined commands sent by the client, or batch them more efficiently to prevent queue buildup.

无效尝试

常见但无效的做法:

  1. Restarting the Redis server without changing buffer limits 90% 失败

    The queue resets temporarily but fills up again under the same load; the error returns.

  2. Increasing maxmemory to allow more memory 85% 失败

    maxmemory does not affect command queue limits; it controls total memory usage.
