Applies to: 
SQL Server
If the value specified for sp_configure 'network packet size' or if the network packet size of any logged-in user is more than 8060 bytes, SQL Server performs different memory allocation operations. This can cause an increase in the process virtual address space that isn't reserved for the buffer pool.
