i have the same exception

[amitguptagwl]

I was also getting the same issue when I was using embedded redis. This thread has useful information.

[punkeel]

Same here, using JedisSentinelPool and Jedis 2.8.1

^- Fixed, timeout (redis config) was improperly setup.

[AaronFeng2014]

why? and i also have this problem, and I dont know why

[marcosnils]

@AaronFeng2014 do you have an example to reproduce your issue?. Usually this is wrong usage of Jedis or miss configuration.

[marcosnils]

@AaronFeng2014 this issue is way too old, please open a new one specifying as much info as possible to reproduce the issue.

[AaronFeng2014]

@marcosnils maybe, ihave too many data in redis?

[justein]

I have meet the same problem,can anyone help?

[amitguptagwl]

Try this

@bean
public JedisPool jedisPool() {
JedisPoolConfig poolConfig = new JedisPoolConfig();
poolConfig.setMaxTotal(threadPoolSize);
poolConfig.setTestOnBorrow(true);
poolConfig.setTestOnReturn(true);
return new JedisPool(poolConfig, host, port, timeout);
}

[songcan]

I have meet the same problem ,who can help me?

[failBoyL]

Is this problem due to the incorrect settings for timeout?

[jondoe1337]

Iam also still facing this problem while doing:

try (Jedis jedis = jedisPool.getResource())
{
    do
        {
            ScanResult<Entry<String, String>> scan = jedis.hscan(regionKey, cursor, new ScanParams().count(50000));

My redis-server timeout is set to 120 and the TCP keepalive is set to 60 (However my linux kernel settings for TCP socket opts are different).

The data I receive is about 450K Hash values - thats why I set the scan params is set to 50K count.

I cannot really reproduce this issue. But it is happening from time to time from different clients (which are not having the exception at the same time).

[jondoe1337]

The problem might be that the jedisPool or in general the connection is too long open and idle. My solution was to open a new connection each time the code is called (which was in my case only once every ten minutes).
