Have been using osTicket for several years now and it had been working fine all the time across software/server upgrades, migrations etc.But this time email piping stopped working when PHP was upgraded from 5.5.x to PHP Version 5.6.18, except for adding mod_geoip to Apache no other settings were changed. PHP is running as DSO (mod_ruid2). All file/folder permissions are correct.I have checked (have root access) emails are being forwarded properly to pipe.php, no error thrown or generated in exim. No error generated by pipe.php, it is just sitting there and doing nothing, no ticket is created, no response/alerts sent.Using web interface to create ticket is working fine, tickets are being created and all responses/alerts are being sent fine.This on a WHM/cPanel CentOS 7.2, Apache 2.4.18PHP 5.6.18MariaDB: 10.1.11 (MariaDB was already there prior to the issue)Used this script to test if something is wrong with piping on the server, but it works fine and it did wrote to /home/username/pipemail.txt=============================#!/usr/bin/php -q<?php/* Read the message from STDIN */$fd = fopen("php://stdin", "r");$email = ""; // This will be the variable holding the data.while (!feof($fd)) {$email .= fread($fd, 1024);}fclose($fd);/* Saves the data into a file */$fdw = fopen("/home/username/pipemail.txt", "w+");fwrite($fdw, $email);fclose($fdw);/* Script End */?>=============================Any ideas, what could be wrong?
