If the svchost process contains more than one service, you will need to break each service out to run in its own svchost process to determine which service is causing the high memory. Scenario B: High memory occurring in svchost.exe process by Heap Get procdump of process when memory is high.The process or service will need to be restarted to put in to effect.Note : Be sure to reverse your gflag setting also by unchecking the “Create user mode stack trace database” when no longer needed. Place check mark in “Create user mode stack trace database.”.Type in the process name, for example notepad.exe.Go to the directory where you installed the tool and you will find gflags.exe as one of the files, right-click on it and select “Run as administrator.”.Just need the standalone version since we only need the debugging tool and not the whole WDK package. Scenario A: Uniquely named process with high memory by Heap If you are not familiar with debugging process dumps, please open a case with Microsoft support for assistance Note: If the high memory shows as Private Data or some other type other than heap, simply continue with getting procdump when memory usage is high.ĭisclaimer: The intent of this blog is not to teach you how to debug. If the high memory is being caused by Heap, you will need to enable User Stack Tracking (UST) against the process using gflags.exe which is part of the Debugging Tools for Windows. Simply launch VMMap and from the process list it displays, pick the instance showing the high private working set.This tool is used to attach to an individual process allowing a snapshot to be taken to see the memory map for that process. It shows a breakdown of a process's committed virtual memory types as well as the amount of physical memory (working set) assigned by the operating system to those types. VMMap is an utility application analyzing virtual and physical memory. Download a Windows Sysinternals tool called VMMap.We need to address the memory types differently. If you have not yet been able to identify where your leak is, please see my blog: MYSTERY MEMORY LEAK: WHERE DID MY MEMORY GO?!įirst thing we need to determine is memory consumption being caused by private data, heap data or some other memory type. This article assumes that you have already identified the process that is leaking. This blog addresses troubleshooting leaks occurring in a process to include identifying and data collection. If a process is hiding in the background, you can click Bring to Front to view its window (assuming it has a visible window).My name is Jeffrey Worline, and I am a Senior Support Escalation Engineer on the Windows Performance Team at Microsoft. If a process is automatically starting with your computer, Process Explorer will tell you where it’s configured to do so. Detailed Process Properties: To view information about a process, right-click it and select Properties.This can help you understand exactly what the process is and where it came from. You can right-click any running process in the list and select Search Online to quickly search for it online. Search Online: This feature is present in Windows 8’s new task manager, but it showed up in Process Explorer first. We won’t focus on all these features – we’ll focus on cool things you can do with Process Explorer that you can’t do with the Windows Task Manager. You can right-click a process to kill it, change its priority level, or set its CPU affinity and force it to run on only a specific CPU. Process Explorer is packed with features, including all the ones you’d expect from the Windows Task Manager.
