Description

This issue was created by maloo for Bob Glossman <[e-mail]>

This issue relates to the following test suite run: https://testing.hpdd.intel.com/test_sets/6bace048-50dc-11e5-95a9-5254006e85c2.

this test fail looks like LU-4499, but that has been marked Fixed. As far as I can tell the fix landed before the mod in this build.
