What does the tieserver-start.log file say?
For your convenience, there is a MER tool included with the TIE Server, look at this KB article: McAfee Corporate KB - How to use the Threat Intelligence Exchange Server MER tool for Linux / UNIX K.... It will collect all logging in one convenient package. I'm not saying you should post the log output here, but the file may help you to see what's going on.
If you don't review that log file, you won't know what might be the issue. If you would be so kind as to post the tail of that file, we might be able to work out the problem. Otherwise, you should open a SR with McAfee Support.
