JBoss Server running very slow.

[Dhrubajyoti Gogoi]

The JBoss server that we are using is running very slow. I tried restarting server, manually cleaning work and tmp folders but the issue till remains. Following is the server log:

This pattern repeats itself.

Looks like you might have set your session timeout to a very small value.

However, I'm not convinced that this is the cause for your performance problems...

I had checked out session time out value and it seems to be fine. Still not able to figure out what is causing the problem.

<!-- ==================== Default Session Configuration ================= -->
  <!-- You can set the default session timeout (in minutes) for all newly   -->
  <!-- created sessions by modifying the value below.                       -->

    <session-config>
        <session-timeout>30</session-timeout>
    </session-config>

What exactly do you mean it is running slow? What are you system configurations and what kind of application(s) have you deployed? What is the user access load?
