No, the application doesn't crash, this is a clean exit. This happens because in the SKYRIX distribution the application is started by the load balancing daemon (snsd), which is not part of OGo.
Update 2004-11-11: Starting with OGo 1.0a alpha releases this issue should not happen anymore, OGo is no preconfigured for automatic restart (using the WOWatchDogEnabled default). Do not set the OGoMinimumActiveSessionCount default as sometimes suggested in the users list.
