- A rapid decline in the SQLServer:Buffer Manager\Page life expectancy performance counter values. When this issue occurs, the counter is near 0.
- The peak value of the SQL Server: Buffer manager\LazyWrites/sec counter is more than 1 for several seconds.
- An increase in the SQLServer:Memory Manager\Free Memory (KB) performance counter values.
This causes a temporary release of more memory than is required to return to a steady state. For example, the buffer pool can release more data pages than required, inflating the free list depths and reducing the page life expectancy (PLE) for the buffer pool. In this situation, you'll notice a quick decline in the SQLServer:Buffer Manager\Page life expectancy performance counter values and a quick increase in SQLServer:Memory Manager\Free Memory (KB) performance counter values.
