redisson异常 Can't init enough connections amount!

使用redisson的时候偶尔遇到这种异常，一天大概几次的样子。断点跟进去是connection time out。
redis 版本：3.0.6
redisson版本：2.2.4
采用master slave，sentinse，single试过都有问题。connection timeout设置为5000都还有问题。
public Redisson getMasterSlaveClient(String add, String hosts) {
Config config = new Config();
String[] hostarr = hosts.split(",");
config.useMasterSlaveServers().setMasterAddress(add).setLoadBalancer(
new RandomLoadBalancer()) // RoundRobinLoadBalancer used by default

.addSlaveAddress(hostarr).setMasterConnectionPoolSize(10000).setSlaveConnectionPoolSize(
10000).setConnectTimeout(5000);
Redisson redisson = (Redisson)Redisson.create(config);
return redisson;
}
