   Queries might be waiting for the pages to be written to the data or log files. In this case, check the `INSTANCE_LOG_RATE_GOVERNOR`, `WRITE_LOG`, or `PAGEIOLATCH_*` wait statistics in the DMV.

 - **Memory-related problems**
 
   If the workload doesn't have enough memory, the page life expectancy might drop, or the queries might get less memory than they need. In some cases, built-in intelligence in Query Optimizer will fix memory-related problems. See using DMVs to [identify memory grant issues](database/monitoring-with-dmvs.md#identify-memory-grant-wait-performance-issues). For more information and sample queries, see [Troubleshoot out of memory errors with Azure SQL Database](database/troubleshoot-memory-errors-issues.md).
