    INETINFO Running at 100%

    Reply Contact

    I am having problems with INETINFO using up all available CPU and slowly bringing my web server to a hault.

    I'm running it on a Windows 2008 server and it works fine most of the time however, at random intervals during the day INETINFO takes over. If I recycle the Application Pool then it eventually recovers. I have tried running Process Monitor and there seems to be continual reads on the C:\Windows\System32\InetSrv\Config\ApplictionHost.config file.

    I've read lots of articles about the SMTP service causing this problem but I have shut this service down which makes no difference. I have also examined the web application code for possible memory leaks, infinite loops etc and have not found anything there either.

     Doe anyone have any ideas what else I should look at.

    If you do not need to use the metabase, you can shut down (and uninstall) iisadmin service and inetinfo will no longer be running - IIS7 itself does not depend on iisadmin.

    As for what is causing the infinite loop, you can use debugdiag to collect a hang dump and analyze it.

    Unfortunately SMTP appears to use the IISAdmin service so I'm not able to shut it down.

    I've tried using debugdiag however, it gives me the following error:

    Script Summary
     
    Script Name Status Error Code Error Source Error Description Source Line
    CrashHangAnalysis.asp Failed 0x80010105

    Line 10097

    Which I think is more to do with DebugDIag not supporting x64 Windows 2008 but I'm nt entirely sure on this.

    Yes, debugdiag for x64 is not yet out - you can use the debugging tools for windows to analyze the hang a bit, it is not going to be as easy to use however - ultimately, unless you are very proficient in using a debugger, I would suggest opening a support case with microsoft support.
