RedisResponseException from BlockingDequeue

在RedisTypedClient上使用BlockingDequeue时，我得到了一个看起来像超时的异常。

调用代码看起来像

 using (var client = ClientPool.GetClient())
    return client.As<TMessage>().Lists[_channel].BlockingDequeue(timeout);

其中超时设置为0，并且ClientPool是PooledRedisClientManager。

堆栈跟踪看起来像

ServiceStack.Redis.RedisResponseException: No more data, sPort: 51100, LastCommand: 
   at ServiceStack.Redis.RedisNativeClient.CreateResponseError(String error)
   at ServiceStack.Redis.RedisNativeClient.ReadMultiData()
   at ServiceStack.Redis.RedisNativeClient.SendExpectMultiData(Byte[][] cmdWithBinaryArgs)
   at ServiceStack.Redis.RedisNativeClient.BRPop(String listId, Int32 timeOutSecs)
   at ServiceStack.Redis.Generic.RedisTypedClient`1.BlockingDequeueItemFromList(IRedisList`1 fromList, Nullable`1 timeOut)
   at ServiceStack.Redis.Generic.RedisClientList`1.BlockingDequeue(Nullable`1 timeOut)

据我所知，这是客户端持有开放连接的问题。我原以为应该使用PooledRedisClientManager来解决这个问题，但它似乎仍然存在。这个问题很容易重现。只需调用BlockingDequeue方法，等待大约2-3分钟，就会抛出异常。

            var redisFactory = new PooledRedisClientManager(redisConn);
            redisFactory.ConnectTimeout = 5;
            redisFactory.IdleTimeOutSecs = 30;
