Symptoms

Assume that you have a database that has a memory-optimized filegroup in Microsoft SQL Server 2014. The transaction log may continue to grow large, and you can't truncate or shrink the log. If you're hitting this issue, you'll see the following symptoms:

  • The sys.databases catalog view reports log_reuse_wait_desc as "XTP_CHECKPOINT."

    Select name, log_reuse_wait_desc from sys.databases where name='<DatabaseName>'
  • A manual checkpoint operation on the affected database fails, and you receive the following error message:

    Msg 41315, Level 16, State 4, Line N
    Checkpoint operation failed in database <database name>.

  • You can't find the offline checkpoint thread that corresponds to the affected database.

    Select db_name(database_id) as DatabaseName, * from sys.dm_exec_requests where command = 'XTP_OFFLINE_CKPT'
  • Querying statistics about the In-Memory OLTP checkpoint operation for the affected database returns 0 for every column:

    Select * from sys.dm_db_xtp_checkpoint_stats
