Vaadin App Hangs when deployed

Felipe26 · September 30, 2014, 11:22pm

Hello,

I am developing a Vaadin App using Vaadin 7, JPAContainer, and MySQL.

When reunning my application in my machine and using it via localhost, the app runs very smooth and no problems arise.

Now I have deployed my app in a Amazon AWS EC2 server using Apache Tomcat as my web server.

The application runs also very nice and smooth (obviously not as fast as in localhost). The problem is, the from time to time, in a random user action (it can be pressing a button in a menu that loads a view, or pressing a button that saves an entity in a user form) the application just hangs. The Vaadin loader indicator (the built in progress indicator bar at the top) starts blinking and never ends and the app simply hangs. In order to continue operation I have to reload the app.

I honestly have no idea what is going on, because the app normaly runs very smooth, but this just happens from time to time and in actions that are very simple and dont requiere any heavy procesing in the server. The funny thing is that it happens in random actions (different every time), and it happens in actions that under normal operation they work just fine.

Any idea what could it be or how could I adress this issue. I have no idea how to detect what is causing this hang or freezing porblem in my app.

I really appreciate any help.

Thax a lot

Hi,

I would start by looking at the server logs, do they say anything? If not, try to run the server with assertions enabled (-ea) to see if there is some kind of synchronization problem - maybe you are updating the UI without properly locking it or something similar.

Hi,
I’m not sure if my problem is related with this thread but as I see some some message in my log file I thought to give it a try.

I’m using Glassfish 4.1 and my application is using Vaadin 7.3.2, push enabled, PreserveOnRefresh enabled.

After Glassfish starts up and I make a fresh deployment everything look fine. After making a second deployment of the same app without restarting Glassfish, I have this messages on my log file:
