Symptoms
Assume that you have a memory-optimized table that uses In-Memory OLTP in Microsoft SQL Server 2014, and the table is included in an AlwaysOn Availability Group. When you try to insert or update many rows in one transaction in this table, a "non-yielding scheduler" error is generated in SQL Server. Additionally, the failover of the AlwaysOn Availability Group occurs, because the dump file generation takes a long time.
