[Kartikaya Gupta (email:[e-mail])]

This started when bug 1176019 first landed, then stopped when it was backed out, and then started again shortly after it re-landed. Pretty sure it's a regression from that.

This should go back down while we disable the work of bug 1176019 with bug 1465106.

Comment 9

[Andrew Overholt [:overholt]]

Cristina, does the recent frequency still fall above the threshold of needing further investigation (I mean, it'd be nice if it were zero failures, but ...)?

Comment 10

[Cristina Coroiu [:ccoroiu]]

The last failure is from 29th May, so I guess it is resolved.
