Error description

• If you try to run "db2licm -l" on the system which has a dual
  core cpu supporting hyperthreading, you will see Number of
  processors = "0" output as follows.
  
    And at this time, you will also see "Cores per socket:2
  Threading degree per core:4" message in db2diag.log and this is
  the eye-catcher for this APAR.
