title: Mongodb hotfix KB2731284
body: <p>I installed MongoDb on a <code>windows server 2008 R2</code> and the <code>hotfix KB2731284</code> is not installed, but I cannot restart the server easily.</p>
  
  <p>In the <code>hotfix</code> description, I got this message "You run an application that uses the <code>FlushViewOfFile()</code> function to clean up memory-mapped files from the paged memory pool." (see <a href="https://support.microsoft.com/en-us/kb/2731284" rel="nofollow">https://support.microsoft.com/en-us/kb/2731284</a>)</p>
  
  <p>My question is, when the funtion <code>FlushViewOfFile()</code> is called? My application is just writing in a collection and get data from it. Do I risk to get some wrong behaviors? </p>
