Openfire on Amazon ec2 ubuntu

Hi,

I am running Openfire 3.9.3 on Ubuntu server 14.04 (Amazon EC2 free tier). Following are other informations on the setup:

Java Version:
1.7.0_65 Oracle Corporation – Java HotSpot™ 64-Bit Server VM
Appserver:
jetty/7.x.y-SNAPSHOT
Host Name:
ip-172*****
OS / Hardware:
Linux / amd64

The openfire just seems to crash for after irregular nintervals. I have been unable to find any reasons for it. Can anyone please help?

Thanks in advance.

As long as the Openfire logs contain no errors you shoul check /var/log/messages,
