Hi Per, yes my app is not design to work with memcache failure. It's also not designe for other appengine failure but that's another story. Even if I did design or if I redesign it to be memcache failure resilient, appengine is also using it for jsp (see the logs in my first message), so : no jsp... Too bad. I'm not going to have other problem with appengine as my app is already rewritten to run on a Tomcat server. I'm still using gwt, but bye-bye appengine and datastore, hello tomcat and mysql.
