当注册十数个以上服务到redis注册中心时，存在很大概率的死锁，程序未能完成所有服务的注册。

当注册十数个以上服务到redis注册中心时，存在很大概率的死锁，程序未能完成所有服务的注册。

@Override

    String key = toCategoryPath(url);
    String value = url.toFullString();
    String expire = String.valueOf(System.currentTimeMillis() + expirePeriod);
    boolean success = false;
    RpcException exception = null;
    for (Map.Entry<String, JedisPool> entry : jedisPools.entrySet()) {
        JedisPool jedisPool = entry.getValue();
        try {
            Jedis jedis = jedisPool.getResource(); //  **HERE! 卡在这里，jedis资源耗尽了？**
            try {
                jedis.hset(key, value, expire);
                jedis.publish(key, Constants.REGISTER);

                if (!replicate) {
                    break; //  If the server side has synchronized data, just write a single machine
                }
            } finally {
                jedis.close();
            }
        } catch (Throwable t) {
            exception = new RpcException("Failed to register service to redis registry. registry: " + entry.getKey() + ", service: " + url + ", cause: " + t.getMessage(), t);
        }
    }
    if (exception != null) {
        if (success) {
            logger.warn(exception.getMessage(), exception);
        } else {
