Ciao a tutti,ho sottoposto lo stesso problema nel forum americano, ma non ho ricevuto risposta. Spero di essere più fortunato qui.Ho configurato un cluster di alfresco (versione 3.2r2) con due nodi. La configurazione è assolutamente standard: il db ed il filesystem sono condivisi e le ehcache sono in cluster (ho utilizzato come base di partenza ehcache-custom.xml.sample.cluster). Ho provato anche a non utilizzare jgroups, ma non è cambiato nulla.Non appena i server cominciano a "parlarsi" nel file di log di entrambi compaiono dei messaggi del tipo:

Le "key" presenti nei messaggi di log spesso si ripetono. Il sistema sembra sostanzialmente bloccato in un loop infinito.Se spengo e faccio ripartire solo uno dei due server, sembra tutto ok e nessun nodo è stato realmente cancellato.Temo che siano state effettuate modifiche su entrambi i nodi quando il cluster non era ancora pronto. Questo potrebbe aver creato dei disallineamenti che adesso non sono più gestibili?Ho visto che esiste una tabella alf_transaction in cui compaiono transazione eseguite su entrambi i nodi.Mi chiedo, nel caso in cui effettivamente il problama sia dovuto a transazioni in conflitto sui due server, se esiste un modo in cui questa tabella può essere "ripulita". A presto,Marco
