Memory leak in Paged Pool memory RRS feed

  • Question

  • Hi All,

    We have a .NET app in IIS being hosted on Windows Server 2012 R2. We've been trying to figure out a memory leak we discovered recently with a graph that looks like "steps".

    Digging in with Process Explorer shows more information about how the memory is being used.  Strangely, though, adding the working set memory listed below in the 2<sup>nd</sup> column of numbers (249.9MB, 96.5MB, 72.3MB, 61.2MB, 61.0MB, 56.7MB, and so on) does not come anywhere near 6,000MB.  And yet, we are using 94% of the 6GB.  So where the heck is other 5GB!?!

     From a Microsoft Technet article, we discovered that it seems the problem is related to “Paged Pool” memory.  4.5GB (yes Gigabytes!) of ram is being used by that - specifically, in svchost.exe.  Interestingly, that is just about all of the “missing ram”!

    (Have a picture but it wouldn't let me post images yet...)

    After discovering that, we've hit a bit of a wall and are not sure how to find out exactly what is causing the leak beyond that it is all gathering in Paged Pool. Are there common causes/processes that would cause a Paged Pool memory leak?   We're kind of at a point where we're not even sure what to ask, specifically, so any feedback would be helpful.

    Thanks!
