title: Play! framework hangs on compile, no errors reported
body: <p>Just moved my app to a new CentOS server. After fiddling for a long time, I can't play to compile or get any errors. The shell output will show me the last file compiling and then hang. I'm running the Scala 0.9.1 module.</p>
  
  <p>I did a <code>strace</code> on the process, this is all I got. Not sure if it helps.</p>
  
  <pre><code>futex(0x410489d0, FUTEX_WAIT, 5403, NULL
  </code></pre>
  
  <p>Any ideas to the cause? Or where I can begin troubleshooting?</p>
  
  <p>Thanks.</p>
