pmap_unwire: wiring for pmap 0xd37e5214 va 0x48115000 didn't change!   
  
What's this "pmap_unwire" error ?  
The server has restarted unexpectedly without errors in logs file.  
Constantly it shows the following error in all terminals:  
syslogd: /dev/:0: No such file or directory

Which the problem ?
