If you enable hyper-threading on a Linux server, a SAS^® installation detects twice the number of actual CPUs.

A SAS installation that uses a sub-capacity license file will fail because the installation detects that the number of allowed CPUs has been exceeded. The following message is generated:

   
   ERROR: The SAS System is executing on a processor (CPU) whose model name, 
          model number, and serial number are not included in the setinit data 
          used to initialize the SAS System library in use. This is permitted 
          if this processor is a designated backup processor for a licensed CPU.

A sub-capacity license queries to determine how many CPUs are available. Enabling hyper-threading causes an incorrect number of CPUs to be returned, and the installation will fail.
