on Jul 19th we see a drop in dromaeo numbers from ~830 -> ~770: http://graphs.mozilla.org/graph.html#tests=[[73,131,33]]&sel=none&displayrange=7&datatype=running sometime in the next day the numbers came back up. I did some retriggers on tbpl: https://tbpl.mozilla.org/?tree=Mozilla-Inbound&fromchange=a692217e595a&tochange=289695fac6be&jobname=Ubuntu%20HW%2012.04%20mozilla-inbound%20talos%20dromaeojs looking at the dromaeo dom numbers we can easily see the regression (the numbers drop) as part of the push: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?changeset=e6b5084690dc I know dromaeo dom holds some value, so far I only see this on linux32.

bz, can you comment if we should look into this or resolve this as wontfix?

this could easily be query.html: https://datazilla.mozilla.org/?start=1405395784&stop=1406044269&product=Firefox&repository=Fx-Team-Non-PGO&os=linux&os_version=Ubuntu%2012.04&test=dromaeo_dom&graph_search=85d5040f1ad2&graph=modify.html.0&x86=true&x86_64=false&project=talos which from looking at some raw data it would be the 4th, 5th and 6th tests have regressed. this revision shows that back to normal: https://tbpl.mozilla.org/?tree=Mozilla-Inbound&rev=0d2f538bddde

If the numbers are back to normal, then this sounds like this is wontfix or worksforme...
