or

severity: warning

message: fwrite(): ssl: broken pipe

filename: models/cron_win_contest_model.php

line number: 386

could please me fix issue

when trying write socket. if goes wrong, fwrite return false or 0 (depending on php version) return value. when happens, must manage it.

by way, add sleep(5) before fwrite().

you can :-

try {                                $result = fwrite($fp, $msg, strlen($msg)); } catch (exception $ex) {     sleep(5); //sleep 5 seconds     $result = fwrite($fp, $msg, strlen($msg));     if ($result)     {         return true;     }     else {         return false;     } } 

hope helps!
