Sql 无法在对象'；dbo.MSmerge#u contents'；具有唯一索引

我们在1个发布服务器和12个订阅服务器之间配置了合并复制，所有订阅服务器都具有SQL server 2008 R2

在其中一个订阅上，我发现以下错误

Error messages:
The merge process could not replicate one or more UPDATE statements to the 'Subscriber' because a stored procedure failed to execute. Troubleshoot by using SQL Profiler. (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147200989)
Get help: http://help/MSSQL_REPL-2147200989
Cannot insert duplicate key row in object 'dbo.MSmerge_contents' with unique index 'nc2MSmerge_contents'. (Source: MSSQLServer, Error number: 2601)
Get help: http://help/2601

在错误中，它提到“

无法在具有唯一索引“nc2MSmerge_contents”的对象“dbo.MSmerge_contents”中插入重复的键行

”我选中了

nc2MSmerge_contents

索引脚本，但没有为索引指定唯一约束

CREATE NONCLUSTERED INDEX [nc2MSmerge_contents] ON [dbo].[MSmerge_contents] 
(
    [generation] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
GO

以下是表格结构

我需要在不删除/重新创建订阅的情况下修复此问题。有人能帮忙吗？问题是数据库和索引已损坏。固定后，下面的链接
