Hi KWierso,

We fxos team are triaging emu-x86-kk test failures, and want to understand if this is the right one to be linked to some emu-x86-kk failures we've observed. 

According to the bug description, it seems this is for tracking an error "This usually indicates the B2G process has crashed"; however, your comment 0 seemed imply that this bug is for *reftests* failures. From the log I learned that the failure pattern seems similar to
   |REFTEST TEST-UNEXPECTED-FAIL | http://10.0.2.2:8888/tests/layout/reftests/bugs/503364-1b.html | image   comparison (==), max difference: 1, number of diiffering pixels: 20|. 

This bug is not exactly for a "crash" but for specific reftests issues. Am I right? Thanks!

This particular instance should actually be resolved fixed as it was caused by the mesa upgrade on the test machines, and that upgrade was reverted. Unsure if there's other failures that have the same failure line, but they should go to some other bug.

Thanks KWierso for the explanation! 

Based on that, I think the pattern I observed on emu-x86-kk mochitest should go to a separate one. Removing the dependency.
