Maloo report: https://maloo.whamcloud.com/test_sets/7209239a-96f3-11e0-9a27-52540025f9af

This is caused by the mismatched clocks between the client and server nodes:

$ pdsh -l root -S -w client-[10,12],fat-amd-[1-2] date
client-10: Tue Jun 14 12:43:33 PDT 2011
client-12: Tue Jun 14 12:43:44 PDT 2011
fat-amd-1: Tue Jun 14 19:43:29 PDT 2011
fat-amd-2: Tue Jun 14 19:43:28 PDT 2011

However, per the comments from Andreas in bug 18169:

This should work correctly so should be investigated, but isn't a release blocking problem.
