死锁：mssqlsystemresource和drop table

Question

这不是原创问题，但我找不到答案。 我遇到了僵局。每次第一次锁定查询时都会显示：

select            
            TABLE_QUALIFIER             = s_cov.TABLE_QUALIFIER,
            TABLE_OWNER                 = s_cov.TABLE_OWNER,
            TABLE_NAME                  = s_cov.TABLE_NAME,
            COLUMN_NAME                 = s_cov.COLUMN_NAME,
            DATA_TYPE                   = s_cov.DATA_TYPE_28,
            TYPE_NAME                   = s_cov.TYPE_NAME_28,
            "PRECISION"                 = s_cov.PRECISION_28,
            "LENGTH"                    = s_cov.LENGTH_28,
            SCALE                       = s_cov.SCALE_90,
            RADIX                       = s_cov.RADIX,
            NULLABLE                    = s_cov.NULLABLE,
            REMARKS                     = s_cov.REMARKS,
            COLUMN_DEF                  = s_cov.COLUMN_DEF,
            SQL_DATA_TYPE               = s_cov.SQL_DATA_TYPE_28,
            SQL_DATETIME_SUB            = s_cov.SQL_DATETIME_SUB_90,
            CHAR_OCTET_LENGTH           = s_cov.CHAR_OCTET_LENGTH_28,
            ORDINAL_POSITION            = s_cov.ORDINAL_POSITION,
            IS_NULLABLE                 = s_cov.IS_NULLABLE,
            SS_DATA_TYPE                = s_cov.SS_DATA_TYPE

        from
            sys.spt_columns_odbc_view s_cov

        where
            s_cov.ODBCVER = @ODBCVer and
            s_cov.OBJECT_TYPE <> 'TT' and
            (@table_name is null or s_cov.TABLE_NAME like @table_name) and
            (@table_owner is null or schema_name(s_cov.SCHEMA_ID) like @table_owner) and
            (@column_name is null or s_cov.COLUMN_NAME like @column_name) and
            ( s_cov.SS_IS_SPARSE = 0 OR objectproperty ( s_cov.OBJECT_ID, 'tablehascolumnset' ) = 0 )

        order by 2, 3, 17

和第二个锁定查询是删除表。每次都有不同的表格：

DROP TABLE TABLE_NAME;

您是否知道它的真正原因或有助于解决或避免问题的事情？ 我在扩展跟踪日志中看不到任何内容。我们使用ms sql server 2008 r2 ... 谢谢你的友好合作。
