Ich führe ein Skript aus, das die Informationen aus Debian-Paketen extrahiert und in einer Datenbank speichert.

Nach dem Extrahieren von Informationen aus ca. 100 Paketen tritt ein Fehler auf. Der Fehler lautet "Ich kann keinen neuen Thread starten". Warum tritt dieser Fehler auf? Was kann die mögliche Lösung dafür sein?

Dies ist der Code zum Speichern der Daten:

for i in list_pack:

      if not i in oblist:        
        #Creating Packages
            slu=slugify(i)
            ob=Gbobject()
            ob.title=i
            ob.slug=slu
            ob.content=''
            ob.tags=tagname
        #with reversion.create_revision():
            ob.save()
            gb=Gbobject.objects.get(title=i)
            gb.objecttypes.add(Objecttype.objects.get(title='Packages'))
            gb.sites.add(Site.objects.get_current())
        #with reversion.create_revision():
            gb.save()
            gd=Gbobject.objects.get(title=i)
            print 'The Object created was',gd


            #Decsription
            try:
                atv=package_description_dict[i]
                atvalue=unicode(atv,'utf-8')
            except UnicodeDecodeError:
                pass
            try:
                lo=Gbobject.objects.get(title=i)
                loid=NID.objects.get(id=lo.id)
            except Gbobject.DoesNotExist:
                pass
            if atvalue<>'':
                slu=slugify(atvalue)
                at=Attribute()
                at.title=atvalue
                at.slug=slu
                at.svalue=atvalue
                at.subject=loid
                att=Attributetype.objects.get(title='Description')
                at.attributetype=att
                #with reversion.create_revision():
                at.save()                    
                print 'yeloow13'

So wieDescriptionEs gibt ungefähr 2 weitere Eigenschaften des Pakets, die auf ähnliche Weise gespeichert werden.

Dies ist der vollständige Traceback, den ich bekomme, wenn der Fehler auftritt:

    error                                     Traceback (most recent call last)
