Hi, Initially I thought that the load balancers in front of Tomcat are not configured with sticky sessions support. This is something normal for services like Google AppEngine, Heroku, and it seems Google Compute Cloud (I'm not sure whether GCC is a completely new service or just the new name of GAE). If this is the case then the problem would be that Wicket Ajax request tries to find a page by id (e.g. url?3) but since the request is handled by a random server in the cloud and most probably there is no session replication it fails to find it.
But org.apache.catalina.connector.ClientAbortException means that the client closed the TCP connection before the server having the chance to write the response. "Client" could be the browser, but also could be a proxy in between. I think it is the latter. What are the reasons exactly I cannot tell.
