Hi @sns ,
From the alert message, which means your server is under a heavy load, the Server service may repeatedly log it in the System Event log. It indicates that the server is out of paged pool memory.
To solve this issue, set the value at 60 informs the Memory Manager in following registry to start the trimming process at 60 percent of PagedPoolMax rather than the default setting of 80 percent.If a threshold of 60 percent isn't enough to handle spikes in activity, reduce this setting to 50 percent or 40 percent.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Memory Management
Restart the server for the changes to take effect.
Note:
Serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it.
