Bug Redis::connect(): connect() failed: Cannot assign requested address

[semprot]

Redis server : 3.2.8
PHP module : redis (3.1.1)
System test >> redis : no error. All are fine.

My redis config file :

$config['Optimise']['redisServers'] = array(
	array('host' => '127.0.0.1', 'port' => 6379)
);

$config['Optimise']['redisMaxDelay'] = 10; // if slave server is out of sync by more than this many seconds, switch to master
//$config['Optimise']['redisTimeout'] = 3; // if redis server doesn't respond in this many seconds, disconnect
$config['Optimise']['redisTimeout'] = 1; // if redis server doesn't respond in this many seconds, disconnect
//$config['Optimise']['redisRetry'] = 100; // retry connection in this many milliseconds
$config['Optimise']['redisRetry'] = 25; // retry connection in this many milliseconds

Error :

According to Google, this is a problem with your server:

Sometimes the "Cannot assign requested address" error can be seen when running out of file descriptors / available TCP ports: are you sure your server is properly configured to handle the current load? If you happen to see a huge number of connections in a TIME_WAIT state by running the following command:

netstat -n | grep TIME_WAIT | wc -l

then you might need to tune your server. Maybe you can try increasing the number of ephemereal ports configured for the TCP stack or setting the TIME_WAIT reuse with /proc/sys/net/ipv4/tcp_tw_reuse, lowering the FIN timeout is a last resort. These are just a couple of ideas, remember to review them according to your current server configuration and the services that are running on it. Check also for the presence of relevant errors in /var/log/messages.

I think you are correct. Even my free RAM percentage is low now.
