I copy and paste the output into Excel, and I turn it into a line graph. I let that run for two days, and then I wacked this bit of perl together to analyze the results: poolmon_ Using ActiveState’s ActivePerl, I set up a scheduled task that ran every fifteen minutes and executed this bit of braindead code that just dumps the output of poolmon.exe to a text file that has the timestamp in the file name: I have no interest in picking up where I left off with Visual C++ ten years ago, so I made do with a little bit of perl and Excel.

Poolmon needs an overhaul: the ability to track growth of values over time, log output to a file, and a GUI would be nice since this is a Windows utility. It’s pure ASCII, runs in a DOS-style command window, can’t log its results over time to a log file and I kid you not, the official way to use this utility to track down leaks is to run it and copy and paste the entire screen output to a text file every fifteen minutes so you can diff the results.

Poolmon has to be the most primitive wacked-up tool anyone at Microsoft has developed, released, and then blatantly ignored. Quite a bit of Google searching and about the only tool I could find that was recommended for tracking down resource leaks that affect the nonpaged memory pool was a Microsoft Utility called poolmon.exe. Process Explorer didn’t yield any immediately useful clues. Task Manager doesn’t display any unusual memory usage. During the melt-down phase the following error is plentiful in the event logs: “The server was unable to allocate from the system nonpaged pool because the pool was empty.” Of the server traits Munin monitors, there doesn’t appear to be anything unusual. Nagios gives a couple of hours advance warning that the server is going to go south, which gives us plenty of time to reboot it. The server is monitored by Nagios, and Munin. Microsoft should fix that in some SP.let's hope soon.Problem: A Windows 2003 Server that starts refusing connections after approximately 14 days of uptime, and if left alone will completely lock up and stop displaying a local console login window.
#CANNOT FIND POOLMON.EXE DRIVER#
Ndu driver was introduced with Win8 and is actually quite buggy in combination with RTL8168 NIC.
#CANNOT FIND POOLMON.EXE DRIVERS#
The following kernel drivers were not loaded in safe mode:Īfter disabling Ndu.sys (Windows Network Data Usage Monitoring Driver) with Autoruns and performing normal boot - voila memory leak has gone!!!! The next step was booting machine in “safe mode with networking” and I was surprised - no more memory leaks!! I made a list of loaded network drivers (using DriverView) and compared it with the list of drivers in normal boot.

Therefore, the culprit is not NIC/WLAN driver at all. I even disabled LAN interface and tried WLAN only -> still memory leak. installed Win8 latest drivers from Realtek -> memory leak remains installed Win7 drivers (Win8 still not supported) from HP official site -> memory leak remains Ģ.
#CANNOT FIND POOLMON.EXE UPDATE#
Laptop has intergrated gigabit NIC from Realtek (RTL8168) so I tried to update it:ġ. Therefore, one of network related driver is a problem, so let’s find which one. The driver tag found by poolmon.exe was “Wfpn” and findstr found “ netio.sys” that is the part of Win8 core networking subsystem. Poolmon.exe showed that non-paged memory grows constantly when copying big files (few 100MB). I used the tool “ poolmon.exe” (part of Windows Driver Kit) to find out which driver is causing the memory leak ( link1, link2, link3). I suspected some third-party network driver is reason for this. Just Chrome browser and MS Word were running most of the mory usage 3.5GB !?!?! The new task manager was showing that the non-paged memory pool raised very fast memory usage stopped at ~3.6GB and then machine started to crawl. When I started to copy big files around LAN (ISO files, AVI.), torrents.

Memory usage at start-up was similar as with Win7 (~1GB of total 4GB) but now the story begins. New Modern UI.nice.polished desktop, speed.nice too. I made a clean installation that took ~20min. Win7 served me perfectly for the last two years and I was quite curious how Win8 (Windows 8 Pro Build 9200 圆4) compares with it.
#CANNOT FIND POOLMON.EXE INSTALL#
Few days after Win8 RTM launch I decided to install it on my old good HP Pavilion DV7 laptop.
