I am using predis, it's subscribed to a channel and listening. It throws the following error (below) and dies after 60 secs exactly. It's surely not my web servers error or its timeout.,How we got to know about this problem ? In php, we were getting "Cannot assign requested address" error while creating a socket (error code 99)., Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers , Stack Overflow Public questions & answers

Just set the read_write_timeout connection parameter to 0 or -1 to fix this. e.g.

$redis = new Predis\ Client('tcp://10.0.0.1:6379'.
   "?read_write_timeout=0");

First I am not sure this is a lumen specific error or a Laravel error too. I have an app running on laravel (5.1) which dispatch jobs, handled by a lumen (5.1) worker.,You may also need to ensure you have the scheme set to tls if appropriate.,I had the same problem. Solved it by installing redis-server on ubuntu, and then starting it using redis-cli ping, Learning Lab →

I think this might be affected by the Predis read_write_timeout parameter, but there is no way to modify that at the moment.

I am using predis and its subscribed to a channel and listening, it throws the error and die , shown below, after 60 secs exaxtly, its surely not my web server error or its timeout. ,Also if i keep using (send data to it and it processes) the worker it doesn't give any error. So its likely a timeout somewhere, and that too in connection.,Setting connection parameters is documented in the README. The author of Redis noted the relevance of the read_write_timeout parameter to this error in an issue on GitHub, in which he notes that:,RedisArray provides consistent hashing and you can select which part of the key is to be used for the distribution.

Here is my code snippet, which is likely producing error, because if data is given to worker it runs this code and go forward, which produces no error after that.

$pubsub = $redis - > pubSub();
$pubsub - > subscribe($channel1);

foreach($pubsub as $message) { //doing stuff here and unsubscribing from channel
}
