Hi. First, I’d like to understand the problem. Are you seeing connection errors or a crash. And if it’s a crash, are you talking about the PHP process crashing or the server?
Next, how are you using PHP? Is it a CLI script (single, multi-process), is it a daemon, is it running in a webserver context (if so which server, and is it PHP-FPM or …)?
Last, it would be helpful to know which OS you’re on, the webserver type and version (if that’s the SAPI you’re using), and which PHP client release?
