Comment 1 Ander Conselvan de Oliveira 2015-05-12 09:02:31 UTC

I believe bug 90254, comment 1 applies here.

Comment 2 lu hua 2015-05-13 02:00:32 UTC

bug 90254 mentions that it takes 25 minutes and doesn't exit testing, also We don't see oom killer. 
I am not sure it's real oom kill or only time out.So report this bug to track oom killer.
I should try to give enough time to run bug 90254.
If you can confirm they are duplication, pls mark as duplicate. Thanks.

Sorry, I re-check bug 90254's dmesg, it has oom killer issue.
