This only happens at the zuul gate. can not reproduce in locally, and don't know how to test the fix..

[Akihiro Motoki (amotoki)]

According to the logstash, it didn't occur in the last 7 days.
The gate had heavy load this week due to FFE merge deadline, but it didn't happen.

I wonder how to reproduce this bug even in the gate.
Mark it "Incomplete" and out of Juno-RC1 target.
