Hello,
 
  I am running FS on a physical server (16 core Xeon) and got the above error. The server runs entOS 5.9, and one of the latest FS gits.
 When I had this message FS was freezing for a while, and active calls lost the voice (I think, can't correlate exactly).
 
1.What does this message means on a non-virtualized server?
2. Can it explain the freeze?
3. What can I do to overcome it?
 
                      Thanks! __Yehavi:
