            I've uploaded a new set of four dumps with Andriy's patch to here:
            ftp.whamcloud.com:/uploads/LU-7382/151223_dumps.tar.gz

            All four nodes which failed had debug enabled. I've included the extracted (and sorted) logs for one of them:

            Cray is seeing this bug regularly during system testing using Lustre 2.7 on a relatively small machine (1 MDT, 8 OSTs, 16 clients). I've uploaded a couple of dumps in case they may be useful in resolving the bug. Location:
