scala - 来自 Redis 客户端 Jedis 的破管道异常

Question

我们有一个来自 Play Framework 应用程序的 redis 客户端调用。此 Redis 调用是由使用 Akka Schedular 的 Actor 发出的。此调度程序每 60 秒运行一次，它会与其他 JDBC 调用一起进行 redis 调用。调度程序运行几分钟后，我们开始在日志文件中看到以下内容，并且应用程序停止响应任何 Redis 客户端调用。这是我第一次接触 Redis，如有任何指点，我们将不胜感激。

redis.host = localhost

redis.port = 6379

redis.timeout = 10

redis.pool.maxActive =110

redis.pool.maxIdle = 50

redis.pool.maxWait = 3000

redis.pool.testOnBorrow = true

redis.pool.testOnReturn = true

redis.pool.testWhileIdle = true

redis.pool.timeBetweenEvictionRunsMillis = 60000

redis.pool.numTestsPerEvictionRun = 10

问题是超时，您用来订阅的客户端超时/被 DC ed。
