Event ID - 802

Event Id802
DescriptionThere is insufficient memory available in the buffer pool.
Event InformationAccording to Microsoft:
This is caused when the buffer pool is full and the buffer pool can not grow any larger.
The following list outlines general steps that will help in troubleshooting memory errors:
Verify whether other applications or services are consuming memory on this server. Reconfigure less critical applications or services to consume less memory.
Start collecting performance monitor counters for SQL Server: Buffer Manager , SQL Server: Memory Manager .
Check the following SQL Server memory configuration parameters:
max server memory
min server memory
awe enabled
min memory per query
Notice any unusual settings and correct them as necessary. Account for increased memory requirements for SQL Server 2005. Default settings are listed in "Setting Server Configuration Options" in SQL Server Books Online.
If you are using Address Windowing Extensions (AWE), verify that the Windows security setting Lock pages in memory is enabled.
Observe DBCC MEMORYSTATUS output and the way it changes when you see these error messages.
Check the workload (number of concurrent sessions, currently executing queries).
The following actions may make more memory available to SQL Server:
If applications besides SQL Server are consuming resources, try stopping these applications or running them on a separate server.
If you have configured max server memory, increase the setting.
Run the following DBCC commands to free several SQL Server memory caches.
If the problem continues, you will need to investigate further and possibly reduce workload.
