Configure the query wait Server Configuration Option
This topic describes how to configure the query wait server configuration option in SQL Server 2014 by using SQL Server Management Studio or Transact-SQL. Memory-intensive queries (such as those involving sorting and hashing) are queued when there is not enough memory available to run the query. The query wait option specifies the time, in seconds (from 0 through 2147483647), that a query waits for resources before it times out. The default value for this option is -1. This means the time-out is calculated as 25 times the estimated query cost.
