i have seen this before, cause is still unclear.. powercycling
rerunning as job 266

  • ceph_direct_io_test (job 266)
    exact same symptoms as with earlier run
    it seems direct_io_test hoses a ceph installation bad enough that exec segfaults reliably

Can't reproduce anymore, apparently some of the recent commits fixed this.
jobs 289 & 290 are both happy. Will re-run over the weekend, re-open on Monday if this really happens again.
