In Archive Manager, you may have issues with your Full Text Index where you see an error in the Full text Indexlogs that is as follows:
System.Data.SqlClient.SqlException: The query processor could not start the necessary thread resources for parallel query execution.
You may get an error about the query processor in SQL not being able to start the necessary thread resources for parallel query execution, when you have The SQL Server configuration option 'max degree of parallelism' set to high for the amount of processors you have on the SQl server
The SQL Server configuration option 'max degree of parallelism' controls the number of processors used for the execution of a query with a parallel plan. This option determines the computing and thread resources used for the query plan operators that can perform the work in parallel. Depending upon whether SQL Server is setup on a Symmetric MultiProcessor Computer [SMP], Non-Uniform Memory Access computer [NUMA] or HyperThreading enabled processors, you will need to configure the 'max degree of parallelism' option appropriately.
