It is hard to tell if this is an actual bug or an artifact of the beta labs test environment, but in recently time the browser tests for MMV in Chrome have been encountering sporadic errors on well-known test images "Error: Could not load image data. http" Examples: 16 October: https://integration.wikimedia.org/ci/job/browsertests-MultimediaViewer-en.wikipedia.beta.wmflabs.org-linux-chrome-sauce/229/testReport/junit/(root)/Navigation/Browsing_back_to_close_MMV_restores_the_scroll_position/ 6 October: https://integration.wikimedia.org/ci/view/BrowserTests/view/-All/job/browsertests-MultimediaViewer-en.wikipedia.beta.wmflabs.org-linux-chrome-sauce/208/ 5 October: https://integration.wikimedia.org/ci/view/BrowserTests/view/-All/job/browsertests-MultimediaViewer-en.wikipedia.beta.wmflabs.org-linux-chrome-sauce/206/testReport/junit/(root)/Basic%20Multimedia%20Viewer%20navigation/Multimedia_Viewer__MMV_/
I suspect this is still beta being unreliable because of HHVM hiccups. We've had sporadic errors like that ever since HHVM was rolled out on beta.

Probably a HTTP 500 on the imageinfo API call. The last test run was Oct 17, 2014 7:29:05 AM. The Apache log for deployment-mediawiki03 doesn't contain anything for that date; no clue if that's the right place to look, though.
Anybody knows if this has happened again in the last 10 days?
Yes, there are a few test failures with this error message every day.
It's actually gotten a lot worse now that I've split the large scenarios into smaller ones following Dan's advice. Just because there are statistically more chances of running into the problem, I guess.
Last successful puppet run on all the cache instances on betalabs was on: The last Puppet run was at Fri Oct 17 10:07:24 UTC 2014 (37931 minutes ago). So this *might* be related? See bug 73263 for info on the puppet issue.
Might be, but there are occurrences of "Could not load image data http" that are older than Oct 17th.
