You’re running CentOS 5, so your disto is quite out of date, and I’m quite hesitant to touch sysadmin there. The correct thing to do is to upgrade to the latest FreePBX Distro. I realise that’s not the easiest thing to do though.
I’ll see what I can do.
Edit: Turns out, nothing. You must upgrade to a modern Distro. This is painless, however, as long as you’ve got the latest Backup and Restore module, you can do a backup of your old machine (with the broken sysadmin), and restore it to a freshly installed Distro machine, and it’ll work without any problems. I’ve spent far too much time caring about backup recently
