Aus bisher ungeklärten Gründen ist der Server, auf dem die Jabber Dienste laufen, viermal in den letzten nichtmal zwei Stunden gecrasht. Von einer auf die andere Sekunde nimmt sich der ejabberd Prozess alle Resourcen, die er kriegen kann, und sogar mehr. 8GB RAM und 8GB virtueller Speicher, alles weg. Plus jede Menge CPU Load. Der Server war so überlastet, dass “top” sich ~ alle 5 Minuten aktualisierte nur letztendlich nur noch ein Hardware Reset half um den Server neu zu starten.<\/p>\n
