Vaadin application not reachable with java.nio.BufferOverflowException

General
1

Hi,

I’m using Vaadin 7.6 with Tomcat 8.5.8. When running the application I have the problem that after some time (greater one day) the vaadin application is no more reachable and the only solution is to restart the Tomcat Server. In the log-files I get the following stack traces below. I added two examples of stack traces which were written when the problem occured. Can anyone help, please? Maybe this problem does not occur with vaadin 8 or I could try some configurations.

Thanks in advance, Robert

Hi,

intermittently occurring errors are always difficult. My personal best guess: it’s either a Proxy timeout, a bug in Atmosphere or a bug Tomcat. Maybe a combination. In the first stacktrace, the last called Vaadin framework code line (at com.vaadin.server.communication.PushHandler.suspend(PushHandler.java:181)) looks like this:

    protected void suspend(AtmosphereResource resource) {
        if (resource.transport() == TRANSPORT.LONG_POLLING) { 
            resource.suspend(getLongPollingSuspendTimeout()); // line 181
        } else {
            resource.suspend(-1);
        }
    }

What does long polling suspend timeout do? From the setter:

    /*
     * Sets the timeout used for suspend calls when using long polling.
     * 
     * If you are using a proxy with a defined idle timeout, set the suspend
     * timeout to a value smaller than the proxy timeout so that the server is
     * aware of a reconnect taking place.
     * 
     * @since 7.6 
     * @param suspendTimeout * the timeout to use for suspended AtmosphereResources 
     */
      public void setLongPollingSuspendTimeout(int longPollingSuspendTimeout) { 
          this.longPollingSuspendTimeout = longPollingSuspendTimeout; 
      }

If you want to try setting your custom longPollingSuspendTimeout, you could maybe override the Atmosphere init parameter
SERVLET_PARAMETER_PUSH_SUSPEND_TIMEOUT_LONGPOLLING (“pushLongPollingSuspendTimeout”) or create a custom PushRequestHandler (see PushRequestHandler.java for more details).

Updating to a newer Vaadin version (and thus a newer Atmosphere) might fix it, but it’s hard to say. And like I said, it could also be a Tomcat-specific issue.

Looking into it further, seems that it’s indeed a Tomcat error:
https://bz.apache.org/bugzilla/show_bug.cgi?id=60372

So updating to a newer version should fix that (e.g.8.5.20, which is the latest). Can you try it out?

No problem, I hope a new Tomcat version solves the issue!

Hi Olli,

thank you very much for this hint. I will update the tomcat as you suggested.

Best regards, Robert
