Erstellung von Thumbnail fehlerhaft

amonts

Hallo Community,

habe mir auf Centos 5.6 das Alfresco Community War 4.0 installiert.
Es funktioniert auch soweit echt gut.
Das Problem ist, dass einige meiner PDFs (Formulare) beim Erzeugen des Thumbnails einen Fehler erzeugen.
Dies wäre nicht soo dramatisch… allerdings muss ich danach immer Tomcat neu starten und das File mittels webdav löschen, da Alfresco komplett den Betrieb verweigert.
Weiss jemand, wie man umstellen kann, dass Alfresco bei so einem Problem komplett abschmiert?

Danke und Gruss

Hallo,
kannst du bitte die genaue Alfresco Version nennen und den Stack-Trace posten der beim Erzeugen der Thumbnail erzeugt wird.
Was genau heisst den "Betrieb verweigert". Nutzt irgendein Prozess die volle CPU o.ä.?

Hallo,

also ich verwende die aktuelle Version 4.0.d

Der Stacktrace ist eigentlich gar nicht sooo wichtig, da es verschiedene Fehler gibt. Eben je nachdem, was am PDF nicht verarbeitet werden kann

Dies ist beispielhaft einer davon…

Mir geht es auch nicht mal unbedingt darum, dass der Preview funktioniert. Was bei mir passiert ist, dass danach Alfresco / Tomcat gar nicht mehr reagieren. Keine Auslastung der CPU oder des Speichers. Einfach nur Tot. Ein Neustart hilft dann.
Tatsächlich hat sich sogar der Prozess komplett verabschiedet… es braucht also gar keinen Neustart… nur ein "Start".

Das erwartete Verhalten wäre einfach, dass angezeigt wird, dass es beim Erstellen des Thumbnails einen Fehler gab und dieser eben nicht erstellt werden konnte.

Danke und Gruss

Hi,
du solltest hier https://issues.alfresco.com ein JIRA-Ticket anlegen bzw ergänzen.
Es gibt einige Tickets zu diesem Thema (bspw https://issues.alfresco.com/jira/browse/ALF-10764).
Was du unbedingt angeben solltest:
- ein Bsp. PDF
- dein Environment
- ein dump von deinem JVM-Crash

VG, Jan
