title: Session problems when APC is turned on
body: <p>We have a problem with PHP session when APC is enabled on our server.</p>
  
  <p>The app works great without APC. However, since we enabled APC, the sessions seems to be getting mixed up when the server experiences heavy load, i.e. users are randomly logging on as another. Everything reverts back to normal once we disabled APC. We can't seem to find anyone with the same problem, except a related problem with these guys (set-cookie was being cached in MS ASP): <a href="http://msdn.microsoft.com/en-us/magazine/cc163577.aspx#S2" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/magazine/cc163577.aspx#S2</a></p>
  
  <p>Anyone else has similar experience? Can you recommend any suggestions?</p>
  
  <p>PS: We have all our sessions handled by files in php.ini. We are also running apache2.</p>
