Published Sep 16 PM If you already determined the process consuming memory, check out my previous blog post: Memory Leaks in a Process Scenario When you cannot reconcile the amount of RAM being used with task manager, resource monitor, or perfmon collection.
Large chunk of RAM being used but you cannot see where or by what. Troubleshooting Scenario A When large amount of RAM is being used by not accounted for in task manager or resource manager. First, when looking in task manager and at the memory usage by processes to view memory usage, ensure you also look in the Memory box on the performance tab — the amount of cached, paged pool, and non-paged pool memory usage.
Glossary and Guide to the column and row headings Stages of memory Active: Pages of physical RAM in active use by the specified category usually a process working set or the system working set.
Standby: Pages of physical RAM not actively being used. These are still left in physical RAM but will be repurposed first by the memory manager either returned to the active list or zeroed out and reused if something needs physical ram for active pages. Modified: Similar to Standby, but these are pages of physical RAM that have been changed and must be flushed to disk before reusing them. Modified no write: Similar to modified pages but have been marked not to write out to disk.
These are usually pages that have been freed by an existing process. Bad: These are physical pages that have been marked as bad. TIP: If you have a memory leak and get to the point of almost running out of memory, the normal procedure is to reboot the machine in order to clear out the memory.
Types of memory usage Process Private: Memory allocated for use only by a single process. Shareable: Pages that have been marked as shared can be used by multiple processes. Paged Pool: Kernel pooled memory that can be paged to disk.
Nonpaged Pool: Kernel pooled memory that cannot be paged to disk. Any link to or advocacy of virus, spyware, malware, or phishing sites. Any other inappropriate content or behavior as defined by the Terms of Use or Code of Conduct.

I've got a Windows 7 machine that keeps running low in RAM. I can see the free RAM going down over a few hours until the point the machine becomes unresponsive.
I've checked the process list and none of them takes that much RAM. I've also checked the number of handles per process and various other indicators but still can't find why the machine runs out of RAM. Here is the result of tasklist a few minutes before the machine becomes unresponsive:.
The high memory usgae comes from a high Page table usage. To see which processes use it, install the Windows Performance Toolkit , open a command prompt as admin and run this command:.
Open the MemUsage. Here you see the processes which have the high pagetable usage. On the right site after the blue line , you see page table memory usage in MB for each process.
