This hotfix lets you raise or lower the kernel memory threshold in Message Queuing.
In certain circumstances, you may want to raise the threshold because an application, a driver, or a system component is consuming kernel memory. Garbage collection is done by the kernel only when the paged pool memory consumption reaches 80 percent. However, Message Queuing stops functioning at 80 percent of paged pool memory consumption. If you set the kernel memory threshold above 80 percent, this makes sure that Message Queuing does not go into "low memory mode" until the Windows Memory Manager starts cleanup.
In other circumstances, you may want to lower the threshold to limit the amount of kernel memory that is used by Message Queuing.
To change the kernel memory threshold, follow these steps:
