I can't make any sense of the failure log: https://build.chromium.org/p/tryserver.chromium.mac/builders/ios-simulator/builds/160528/steps/ios_web_unittests%20%28iPad%20Air%202%20iOS%2010.0%29/logs/stdio Sana, Serget, do you have any idea why swarmint times out?

Hmm... My first thought was capacity, but this pool looks pretty healthy, especially at 1:28am: http://shortn/_nBL6vnhmv1 The task was assigned a bot, but the bot didn't finish in 20min and got killed. The same bot runs a bunch of other tasks just fine and pretty fast, so the machine itself is likely OK. Incidentally, the machine got rebooted right after this task timed out: https://goto.google.com/crnbk (see the uptime graph). The tasks before or after this failure seem healthy, so this must be just a regular reboot. *shrug*

And the logs on the task page https://chromium-swarm.appspot.com/task?id=34831e1ad195ad10&refresh=10&show_raw=1 are surprisingly short: Device wiped. /b/s/w/irWHkc5O/src/out/Debug-iphonesimulator/iossim -d iPad Air 2 -s 10.0 /b/s/w/irWHkc5O/src/out/Debug-iphonesimulator/ios_web_unittests.app User defaults from command line: IDETestRunSpecificationPath = /var/folders/p4/py6nlvcx4fs5s3fg51_pzqmc0000gm/T/7D0D96FD-123A-4ECF-AF64-26AFE331C68E The simulator hung, maybe?

Rohit, have you seen failures like this before?

In re #2: the timeout is because the task hung for too long with no output. Looking at the logs (https://chromium-swarm.appspot.com/task?id=34831e1ad195ad10) we see that iossim was invoked and hung until the task timed out.

Assigning to Rohit, who owns iossim.
