    这是一个创建于 623 天前的主题,其中的信息可能已经有所发展或是发生改变。

    java 应用,生产者单线程分页查询数据库并写入 redis 队列中,消费者 30 个线程多线程消费 list 。本来是没有出现过这个报错的,但是更新了生产者的 sql 后,sql 速度变快了?每次正常运行一段时间后,生产者异常就出现,消费者也接着出现异常

    报的异常如下

    生产者异常: :"sendQueueMessageInfo leftPushAll : 异常 : org.springframework.data.redis.RedisConnectionFailureException: Unexpected end of stream.; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Unexpected end of stream. org.springframework.data.redis.connection.jedis.JedisExceptionConverter.convert(JedisExceptionConverter.java:67) org.springframework.data.redis.connection.jedis.JedisExceptionConverter.convert(JedisExceptionConverter.java:41) org.springframework.data.redis.PassThroughExceptionTranslationStrategy.translate(PassThroughExceptionTranslationStrategy.java:44) org.springframework.data.redis.FallbackExceptionTranslationStrategy.translate(FallbackExceptionTranslationStrategy.java:42) org.springframework.data.redis.connection.jedis.JedisConnection.convertJedisAccessException(JedisConnection.java:142) org.springframework.data.redis.connection.jedis.JedisListCommands.convertJedisAccessException(JedisListCommands.java:486) org.springframework.data.redis.connection.jedis.JedisListCommands.lPush(JedisListCommands.java:84) org.springframework.data.redis.connection.DefaultedRedisConnection.lPush(DefaultedRedisConnection.java:444) org.springframework.data.redis.core.DefaultListOperations.lambda$leftPushAll$2(DefaultListOperations.java:124) org.springframework.data.redis.core.RedisTemplate.execute(RedisTemplate.java:224) org.springframework.data.redis.core.RedisTemplate.execute(RedisTemplate.java:184) org.springframework.data.redis.core.AbstractOperations.execute(AbstractOperations.java:95) org.springframework.data.redis.core.DefaultListOperations.leftPushAll(DefaultListOperations.java:124) com.service.ds.exec.DataSourceActuator.sendQueueMessageInfo(DataSourceActuator.java:392) com.service.ds.exec.DataSourceActuator.execAndPushQueue(DataSourceActuator.java:214) com.controller.rest.etl.EtlTaskRestController$1.run(EtlTaskRestController.java:86) java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) java.lang.Thread.run(Thread.java:745)\

    据观察 jedispool 的 NumActive:31NumIdle:8 数量都还算稳定 和正常?

    config get timeout
    1) "timeout"
    2) "0"

    config get client-output-buffer-limit
    1) "client-output-buffer-limit"
    2) "normal 0 0 0 slave 268435456 67108864 60 pubsub 33554432 8388608 60"

    额 ,是 redis list 太大了, 超过了 redis 分配内存 4g ,导致 redis 重启服务,然后拿不到链接
