Server Start Error for Ejabberd

Hi all,

I have a VPS dedicated server. I installed Ejabberd server in a folder named: Ejabberd. Now, when I try to start the Ejabberd server, it gives me an error. Here is the error details from the 'Install.log'.

Executing final installation script
Error executing post installation script
/ejabberd/bin/postinstall.sh
\child process exited abnormally
Creating Uninstaller

The error log file has the following information:
