Some frequently reported architectural limits in Windows include the following:. However, Windows Vista, Windows Server , and Windows 7 do not all share these architectural limits.
The limits on user and kernel memory numbers 1 and 2 here are the same, but kernel resources such as PTEs and various memory pools are dynamic. This new functionality enables both paged and nonpaged memory. This also enables PTEs and session pool to grow beyond the limits that were discussed earlier, up to the point where the whole kernel is exhausted. This may be true in some cases. However, you have to monitor your system to know whether they apply to your particular system or not.
In some cases, these statements are conclusions from specific Windows NT 4. Significant changes were made to Windows Server to reduce the probability that these architectural limits will in fact be reached in practice.
For example, some processes that were in the kernel were moved to non-kernel processes to reduce the memory used in the shared virtual address space. Performance Monitor is the principle tool for monitoring system performance and for identifying the location of the bottleneck.
Here is a summary of some important counters and what they tell you:. This shows how many bytes were allocated by processes and to which the operating system has committed a RAM page frame or a page slot in the pagefile or perhaps both. As Committed Bytes grows greater than the available RAM, paging will increase, and the pagefile size that is being used will also increase.
At some point, paging activity starts to significantly affect performance. This value is always a multiple of 4,, which is the page size that is used in Windows. As demand for virtual memory increases beyond the available RAM, the operating system adjusts how much of a process's virtual memory is in its Working Set to optimize available RAM usage and minimize paging.
And one more, i have been using poolmon. Plus all processes in the kernel memory is crucial and cannot be terminated. I really hope that any of you could help me with this problem.

Additionally, you might see the following symptoms: -You might be able to ping the server -You might not be able to open a network share -You might not be able to login to the server via a Remote Desktop RDP session.
What is Paged pool memory? Paged pool memory is a kernel memory that gets calculated during boot time. If the problem continues, then go on to the next data gathering steps. The highest tag is named Leak Notice that the Leak tag is allocating Allocs 26 and not freeing Frees any 0. So you know the tag, now what? Who is using this tag? Notice that the driver is named MyFault. This is what the O. Share this: Twitter Facebook. Like this: Like Loading This entry was posted in Uncategorized.
From there it is easy to query for things like free PTEs, usage and maximum of non- paged pool. Sign up to join this community. The best answers are voted up and rise to the top.
