Comments

[Lai Siyao]

This doesn't show up again after LU-4340 gets fixed, let's close it.

[Andreas Dilger]

LU-4340 is fixing test_69, so likely this can be closed when that is landed.

[Jian Yu]

After except conf-sanity test 69, the tests passed:
https://testing.hpdd.intel.com/test_sets/d6a1d7ea-330a-11e5-a247-5254006e85c2

[Oleg Drokin]

I suspect this might be another manifestation of LU-5420.

[Lai Siyao]

maloo logs don't provide any useful information, and I can't reproduce it in local system.

Lai,
Could you please have a look at this one?
Thank you!

[Jian Yu]

conf-sanity test 76a hit the same failure.
