To prevent multiple deadlocks on our database (MSSQL Server) we switch isolation level to snapshot isolation. And now we are getting following multiple messages in a log-file:

2008-09-10 09:48:10,221 ERROR [TP-Processor16] [atlassian.xwork.interceptors.XWorkTransactionInterceptor] onThrowable Invoking rollback for transaction on action '/pages/viewpage.action (ViewPageAction.execute())' due to throwable: org.springframework.jdbc.BadSqlGrammarException: Hibernate operation: could not update: [bucket.user.propertyset.BucketPropertySetItem#bucket.user.propertyset.BucketPropertySetItem@ccf6bf53]; bad SQL grammar []; nested exception is java.sql.SQLException: Snapshot isolation transaction aborted due to update conflict. You cannot use snapshot isolation to access table 'dbo.OS_PROPERTYENTRY' directly or indirectly in database 'Confluence_2_9' to update, delete, or insert the row that has been modified or deleted by another transaction.
