In that moment the labs instance in question had only few MB free memory out of 2 GB because 700 MB (and 1000 virtual) were taken by puppet... No idea if this should be considered a bug or we should just advise people to have more RAM.
Comment 1 Antoine "hashar" Musso (WMF) 2014-07-28 09:26:33 UTC 
Seems related to vagrant setup, not bug 67216 which is about having extensions pass tests together.
Comment 2 Kunal Mehta (Legoktm) 2014-07-29 00:25:04 UTC 
I don't think Echo can do much about this since we're just using wfDiff. It would be nice if we could benchmark how much memory Echo needs...
