title: MySQL Can't create a new thread (errno 12)
body: <p>I'm runnning MySQL 5.0.45/ PHP Version 5.2.6 / CentOS with Plesk.</p>
  
  <p>I get occasionaly a burst of "Can't create a new thread (errno 12); if you are not out of available memory, you can consult the manual for a possible OS-dependent bug"</p>
  
  <p>Global memory is not the issue since I have about 620M free.</p>
  
  <p>Anyone know what could be the cause for this?</p>
  
  <p>Thanks</p>
