Occasional test time out on ios-simulator
Project Member Reported by timloh@chromium.org, Jan 11 2017 Back to list
The ios-simulator bot seems to be occasionally timing out tests that otherwise take <10s.

https://build.chromium.org/p/chromium.mac/builders/ios-simulator?numbuilds=200

Seven failures in the last 200 builds:
Failed steps failed ios_net_unittests (ipad air 2 ios 10.0)
Failed steps failed gfx_unittests (ipad air 2 ios 10.0)
Failed steps failed gfx_unittests (ipad air 2 ios 10.0)
Failed steps failed google_apis_unittests (ipad air 2 ios 10.0)
Failed steps failed sql_unittests (ipad air 2 ios 10.0)
Failed steps failed ios_chrome_unittests (ipad air 2 ios 10.0)
Failed steps failed components_unittests (iphone 6s ios 10.0)

 
Status: Available
This seems to happen a few times a week at peak hours: http://shortn/_5ypWTgEdWh (though the peaks might be clumping several failures together)

Looking at a few timed out shards, I see that they were running (so it's not a capacity issue), just running for way too long with no response from the bot. Maybe the bots are dying mid-test and never respond?
 Issue 690746  has been merged into this issue.

It's still happening today. https://build.chromium.org/p/chromium.mac/builders/ios-simulator/builds/14392

I notice that this issue (https://bugs.chromium.org/p/chromium/issues/detail?id=624363) keeps rolling in commits touching tests on ios. Not sure if this is related. stkhapugin@: Mind take a look at it?

This is a bug with tens of commits related to ARC transition, that happen to be tests in the past few weeks but is not limited to tests. I don't think it is related.

It seems like this is caused by flaky tests? Is there any action desired from a trooper here? 
Labels: -Infra-Troopers
No trooper action is needed here. The iossim invocations are just hanging.
Another instance today:
https://uberchromegw.corp.google.com/i/chromium.mac/builders/ios-simulator/builds/16338

It doesn't look like any tests were actually run, something in the setup of the device seems to have stalled.
Filed  issue 709374  since it seems different from this issue.
