title: jps returns no output even when java processes are running
body: <p>I'm trying to debug some issues with java processes on a Solaris box, but running jps returns no output. And jstack gives the error 'Permission denied'. The box is part of a cluster of 3 identical servers, jps and jstack work fine on the 2 other servers.</p>
  
  <p>I found the following forum post from someone with the same problem but no answers:

  <p>To clarify running bps and grep for java gives all java proceses correctly, but jps gives nothing (anonymised with 'program' and 'client' to protect the guilty):</p>

  <p>I asked around and from here <a href="http://forums.oracle.com/forums/message.jspa?messageID=5408592" rel="noreferrer">http://forums.oracle.com/forums/message.jspa?messageID=5408592</a> I've got that the issue is:</p>
  
  <pre><code>12460/2: mkdir("/tmp/hsperfdata_program", 0755) Err#13 EACCES [ALL]
  </code></pre>
  
  <p>Meaning jps is being denied access to the psperfdata directory.</p>
  
  <p>Has anyone run into this issue and know how to solve it?</p>
