Broken pipe while using Jedis Pool

Question

I'm using Jedis to perform a lot of insertions/reads in Redis. The Redis server is using the default configuration. The problem appears when I start using a few threads and the exception is:

redis.clients.jedis.exceptions.JedisConnectionException: java.net.SocketException: Pipe quebrado (Write failed)

I've searched a lot about this problem but couldn't find the reason of it or it's solve. The code I'm using to perform these tests is below:

public class RedisFacade {

private static RedisFacade instancia = null;
// Initialize the Connection
final JedisPoolConfig poolConfig = buildPoolConfig();
JedisPool pool = new JedisPool(poolConfig, "localhost");
Jedis jedis;
int i = 0;

private RedisFacade() {
}

public static RedisFacade getInstancia() {
    if (instancia == null) {
        instancia = new RedisFacade();
    }
    return instancia;
}

// retorna um cliente jedis da pool
public Jedis getDB() {
    if (jedis == null) {
        jedis = pool.getResource();
    }
    return jedis;
}

//inserting
public void insert(Document d) {
    String key = i + d.getString("date") + d.getString("time");
    String value = d.toString();
    this.getDB().set(key, value);
    i++;
}

//reading
public void read(String date, String time) {
    Object doc = this.getDB().get(i + date + time);
    i++;
    System.out.println(doc);
}

public void destroyPool() {
    this.pool.destroy();
}

private JedisPoolConfig buildPoolConfig() {
    final JedisPoolConfig poolConfig = new JedisPoolConfig();
    poolConfig.setMaxTotal(1100);
    poolConfig.setMaxIdle(16);
    poolConfig.setMinIdle(16);
    poolConfig.setTestOnBorrow(true);
    poolConfig.setTestOnReturn(true);
    poolConfig.setTestWhileIdle(true);poolConfig.setMinEvictableIdleTimeMillis(Duration.ofSeconds(60).toMillis());
    poolConfig.setTimeBetweenEvictionRunsMillis(Duration.ofSeconds(30).toMillis());
    poolConfig.setNumTestsPerEvictionRun(3);
    poolConfig.setBlockWhenExhausted(true);
    return poolConfig;
}}

Seems like it's a timeout issue.

See this thread: Configure Jedis timeout

And also this discussion: https://github.com/xetorthio/jedis/issues/185

So I would try instantiating JedisPool with a timeout parameter (i.e. https://github.com/xetorthio/jedis/blob/master/src/main/java/redis/clients/jedis/JedisPool.java#L201, but there are many other constructors)

and setting CONFIG SET timeout 600 in redis (with a 10 minute timeout for instance).

Edit

The JedisPool timeout is in milliseconds it seems.
