====================
To resolve this problem, modify the registry to increase the PoolUsageMaximum value and the PagedPoolSize value. To do this, follow these steps:
1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
3. On the Edit menu, point to New, and then click DWORD Value.
4. In the New Value #1 box, type PoolUsageMaximum, and then press ENTER.
5. Right-click PoolUsageMaximum, and then click Modify.
6. In the Value data box, type 60, and then click OK.
(Setting the value at 60 informs the Memory Manager to start the trimming process at 60 percent of PagedPoolMax rather than the default setting of 80 percent. If a threshold of 60 percent is not enough to handle spikes in activity, reduce this setting to 50 percent or 40 percent.)
7. If the PagedPoolSize registry entry exists, go to step 8. If the PagedPoolSize registry entry does not exist, create it. To do this, follow these steps:
On the Edit menu, point to New, and then click DWORD Value.
In the New Value #1 box, type PagedPoolSize, and then press ENTER.
8. Right-click PagedPoolSize, and then click Modify.
9. In the Value data box, type ffffffff, and then click OK.
10. Exit Registry Editor, and then restart the computer.
