Was kann ich bei der Fehlermeldung "IOException while loading persisted sessions" tun?
Falls Gentics Portal.Node gestoppt werden mussten und somit auch der Tomcat heruntergefahren wird, versucht dieser die aktiven Sessions zu speichern. Da aber nicht alle Daten einer Session serialisierbar (grob gesagt in eine Datei oder Datenbank speicherbar) sind und Tomcat beim erneuten Start versucht diese Session wiederherzustellen kommt es zu folgender Fehlermeldung:
- IOException while loading persisted sessions: java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: com.gentics.lib.datasource.WrapDatasource

Um diesen Problem Herr zu werden, kann versucht werden Gentics Portal.Node neu zu starten wobei vorher jedoch das work-Verzeichnis von Tomcat gelöscht werden sollte (/Node/tomcat/work). Anschließend sollte Tomcat wieder sauber starten.
