Since you don't tell us what that server is running, or give anything more than a single INFO message line of a log file, there's not much we can tell you. Short answer: there's a Java program that's misbehaving...fix it. Long answer: call Red Hat support, since you're PAYING for Red Hat Enterprise, right??? They can help you run traces and analyze things to help you diagnose problems.
