Description Greg Nichols 2010-08-18 19:42:07 UTC
Description of problem:

threaded_memtest.c uses _SC_NPROCESSORS_CONF to determine the number of processors, where it should be using _SC_NPROCESSORS_ONLN.   In RHEL6,
these two values differ.

Version-Release number of selected component (if applicable):

v7 1.2 R17
RHEL6 snapshot 7
