Fehler "core.ERROR: exception 'Zend_Currency_Exception'"

Hallo, ich möchte mich der Fehlersuche anschließen. Gibt es zu der Problematik ein Update? Aus dem heiteren Himmel konnten bei mir zunächst jegliche Listing-Seiten oder Artikel-Detailsseiten nicht mehr angezeigt werden (“Ups, es ist ein Fehler aufgetreten…”), immerhin gingen noch Seiten wie die Einkaufswelten, Kontakt etc. Im Log hieß es: [2015-01-07 16:47:12] core.ERROR: exception ‘Zend_Session_Exception’ with message ‘The session has already been started. The session id must be set first.’ in /www/htdocs/xxxxxx/shopware/engine/Library/Zend/Session.php:709 Nach Löschen des Caches “Proxies und Meta-Daten” lief dann wieder alles wieder. Doch kurze Zeit darauf (1-2 Tage) ging dann gar nichts mehr: Keine Frontend-Seite war mehr erreichbar. Immerhin war das Backend erreichbar. Hier wiederum hat das Löschen des Caches “Proxies und Meta-Daten” erneut Besserung gebracht. Nun lautete die Fehlermeldung: [2015-01-08 09:34:13] core.ERROR: exception 'Zend\_Currency\_Exception' with message 'Currency 'EUR' not found' in /www/htdocs/xxxxxx/shopware/engine/Library/Zend/Currency.php:124 Stack trace: #0 /www/htdocs/xxxxxx/shopware/engine/Shopware/Components/DependencyInjection/Bridge/Currency.php(49): Zend\_Currency-\>\_\_construct('EUR', Object(Zend\_Locale)) #1 /www/htdocs/xxxxxx/shopware/cache/proxies/Shopware201409241139ProductionProjectContainer.php(132): Shopware\Components\DependencyInjection\Bridge\Currency-\>factory(Object(Shopware201409241139ProductionProjectContainer), Object(Zend\_Locale)) #2 /www/htdocs/xxxxxx/shopware/vendor/symfony/dependency-injection/Symfony/Component/DependencyInjection/Container.php(312): Shopware201409241139ProductionProjectContainer-\>getCurrencyService() #3 /www/htdocs/xxxxxx/shopware/engine/Shopware/Components/DependencyInjection/Container.php(253): Symfony\Component\DependencyInjection\Container-\>get('currency') #4 /www/htdocs/xxxxxx/shopware/engine/Shopware/Components/DependencyInjection/Container.php(188): Shopware\Components\DependencyInjection\Container-\>load('currency') #5 /www/htdocs/xxxxxx/shopware/engine/Shopware/Bootstrap.php(149): Shopware\Components\DependencyInjection\Container-\>get('Currency') #6 /www/htdocs/xxxxxx/shopware/engine/Shopware/Models/Shop/Shop.php(679): Shopware\_Bootstrap-\>getResource('Currency') #7 /www/htdocs/xxxxxx/shopware/engine/Shopware/Plugins/Default/Core/Router/Bootstrap.php(167): Shopware\Models\Shop\Shop-\>registerResources(Object(Shopware\_Proxies\_ShopwareBootstrapProxy)) #8 /www/htdocs/xxxxxx/shopware/engine/Library/Enlight/Event/Handler/Plugin.php(149): Shopware\_Plugins\_Core\_Router\_Bootstrap-\>onRouteStartup(Object(Enlight\_Controller\_EventArgs)) #9 /www/htdocs/xxxxxx/shopware/engine/Library/Enlight/Event/EventManager.php(211): Enlight\_Event\_Handler\_Plugin-\>execute(Object(Enlight\_Controller\_EventArgs)) #10 /www/htdocs/xxxxxx/shopware/engine/Library/Enlight/Controller/Front.php(170): Enlight\_Event\_EventManager-\>notify('Enlight\_Control...', Object(Enlight\_Controller\_EventArgs)) #11 /www/htdocs/xxxxxx/shopware/engine/Shopware/Kernel.php(141): Enlight\_Controller\_Front-\>dispatch() #12 /www/htdocs/xxxxxx/shopware/vendor/symfony/http-kernel/Symfony/Component/HttpKernel/HttpCache/HttpCache.php(472): Shopware\Kernel-\>handle(Object(Symfony\Component\HttpFoundation\Request), 1, true) #13 /www/htdocs/xxxxxx/shopware/engine/Shopware/Components/HttpCache/AppCache.php(256): Symfony\Component\HttpKernel\HttpCache\HttpCache-\>forward(Object(Symfony\Component\HttpFoundation\Request), true, NULL) #14 /www/htdocs/xxxxxx/shopware/vendor/symfony/http-kernel/Symfony/Component/HttpKernel/HttpCache/HttpCache.php(429): Shopware\Components\HttpCache\AppCache-\>forward(Object(Symfony\Component\HttpFoundation\Request), true) #15 /www/htdocs/xxxxxx/shopware/vendor/symfony/http-kernel/Symfony/Component/HttpKernel/HttpCache/HttpCache.php(329): Symfony\Component\HttpKernel\HttpCache\HttpCache-\>fetch(Object(Symfony\Component\HttpFoundation\Request), true) #16 /www/htdocs/xxxxxx/shopware/engine/Shopware/Components/HttpCache/AppCache.php(178): Symfony\Component\HttpKernel\HttpCache\HttpCache-\>lookup(Object(Symfony\Component\HttpFoundation\Request), true) #17 /www/htdocs/xxxxxx/shopware/vendor/symfony/http-kernel/Symfony/Component/HttpKernel/HttpCache/HttpCache.php(193): Shopware\Components\HttpCache\AppCache-\>lookup(Object(Symfony\Component\HttpFoundation\Request), true) #18 /www/htdocs/xxxxxx/shopware/engine/Shopware/Components/HttpCache/AppCache.php(113): Symfony\Component\HttpKernel\HttpCache\HttpCache-\>handle(Object(Symfony\Component\HttpFoundation\Request), 1, true) #19 /www/htdocs/xxxxxx/shopware/shopware.php(109): Shopware\Components\HttpCache\AppCache-\>handle(Object(Symfony\Component\HttpFoundation\Request)) #20 {main} [] {"uid":"2f9aaf3"}
