title: "Insufficient memory or insufficient privileges to attach " when capture the tomcat dump
body: <p>I tried to capture the tomcat process dump with jmap , however I got the error " Insufficient memory or insufficient privileges to attach" , obviously there is enough memory, and the currently login user is in the role local administrator group. If I run the cmd command as administrator, it still failed.</p>
  
  <pre><code>C:\Program Files\Java\jdk1.7.0_71\bin&gt;jmap.exe -dump:format=b,file=d:\temp\HeapD
  ump.hprof 30452
  30452: Insufficient memory or insufficient privileges to attach
  The -F option can be used when the target process is not responding
