--------------------------------------
Summary: Server crashed after long wait, while reloading widget
Key: WOOKIE-404
URL: https://issues.apache.org/jira/browse/WOOKIE-404
Project: Wookie
Issue Type: Bug
Components: Server
Affects Versions: 0.16.0
Environment: Java vm 6.x, tomcat 6.0.36
Reporter: Gonzalo Aguilar
Server crashed after reloading a widget.
Situation is as follows:
1.-) Widget loaded in a portal. In my case Rave but I suppose it will do the
same in whatever portal you try.
2.-) Once the widget is loaded I leaved it overnight.
3.-) I tried to reload the widget (by moving it). So the server initiated a
reload.
4.-) Stack trace as follows.
Expected behavior is take over db connection and reconnect if neccesary.
