Recently Microsoft has published a ”FAST PUBLISH” article about User Profile Application service starting problem with FIM Syncronization service.In KB defined problem is caused by The ‘Recursive Triggers Enabled’ property for the Model database is set to ‘True’ in the SQL instance. And the error is in your application log
The server encountered an unexpected error and stopped.
“ERR: MMS(6016): sql.cpp(5580): Query (update [mms_run_history] set [is_run_complete] = 1,[run_result] = N’stopped-server’,[end_date] = <Date & Time> where ([is_run_complete] = 0)) performed with error

What is a Recursive Triggers ?
A requirsive trigger is a trigger that fired by the other triggers or intreacting object that fire the trigger when executed recursively.
SQL Server also allows for recursive invocation of triggers when the RECURSIVE_TRIGGERS setting is enabled using ALTER DATABASE.
Recursive triggers enable the following types of recursion to occur:
- Indirect recursion
With indirect recursion, an application updates table T1. This fires trigger TR1, updating table T2. In this scenario, trigger T2 then fires and updates table T1. - Direct recursion
With direct recursion, the application updates table T1. This fires trigger TR1, updating table T1. Because table T1 was updated, trigger TR1 fires again, and so on.
The following example uses both indirect and direct trigger recursion Assume that two update triggers, TR1 and TR2, are defined on table T1. Trigger TR1 updates table T1 recursively. An UPDATE statement executes each TR1 and TR2 one time. Additionally, the execution of TR1 triggers the execution of TR1 (recursively) and TR2. The inserted and deleted tables for a specific trigger contain rows that correspond only to the UPDATE statement that invoked the trigger.
Note:The previous behavior occurs only if the RECURSIVE_TRIGGERS setting is enabled by using ALTER DATABASE. There is no defined order in which multiple triggers defined for a specific event are executed. Each trigger should be self-contained.
If any one of the triggers performs a ROLLBACK TRANSACTION, regardless of the nesting level, no more triggers are executed.
How to change “Recursive Triggers Enabled” property to false ?
From the SQL Server Management Studio, expand ‘System Databases’ > Right-click ‘Model’ | Properties | Options | under Miscellaneous section, set ‘Recursive Triggers Enabled’ property to ‘False’.
or.
The recursive trigger setting works on a database level . For checking the status of the recursive setting, use this command:
EXEC sp_dboption '<name of db>', 'recursive triggers' -for enabling Recusive Triggers:
EXEC sp_dboption '<name of db>', 'recursive triggers', 'true' for disabling Recursive Triggers:
EXEC sp_dboption '<name of db>', 'recursive triggers', 'false' For our senario use like this:
EXEC sp_dboption 'Model', 'recursive triggers', 'false' Resources:
