This failure almost always occurs on osx debug e10s. Failures appear to have started with the update to tests in bug 1344294.

These are NOT normally long-running tests on this platform:

TEST-OK | devtools/client/debugger/new/test/mochitest/browser_dbg-sourcemaps.js | took 15686ms


Failure screenshots show the browser with one new tab and the spinner.

Failure logs typically end like:

...

thanks for working on this :jlast, if you need more info on the failure rates or patterns, I am happy to help.

Thanks :jmaher, i'm fairly new to intermittents and this is an interesting one too. Some questions I have are:

* what's the frequency, are there platforms that are more common. 
* is it mostly / exclusively debug mode?
* are there differences between the devtools/client/debugger/new intermittents or are they equally likely and un-correlated

Also, if you could give me a set of bad try runs i could use that to search through the logs.
these are almost all on osx debug e10s tests, a few instances of win8/linux64 debug e10s as well.  

I am not sure if this is related to any other devtools/client/debugger/new intermittents, but looking there are 23 of them:
https://bugzilla.mozilla.org/buglist.cgi?quicksearch=devtools%2Fclient%2Fdebugger%2Fnew&list_id=13482647

I do wonder if this is a simple fix to clean them all up as they seem to be osx debug related- they all started around the same time.

Here is a way to look at all the failures we have found for a given bug:

either bug 1344563, bug 1331342, bug 1341994, or bug 1344294.  Possibly bisect it down if reading the source doesn't help much?

:jlast, any updates here?

:jdescottes and I are looking into this.

something greatly reduced the frequency here!  pulling it off my radar for now.
