EC2 AMI agent failures on startup

[pmeenan]

Can you tell what version of the agent is running? http://<server>/getTesters.php will list the software version. For Chrome/Firefox/modern IE (wptdriver) the current version is 2.19.0.268

When the EC2 agents start up, they install the current release of Chrome and Firefox and then when they poll the server for work the server will send down a software update if they are not running the current version.

Docs for updating the server to the latest agents are here: https://sites.google.com/a/webpagetest.o...est-Agents

Optionally, if you are running a recent release (2.19 certainly, maybe 2.18) you can enable a setting in settings.ini on the server to have it automatically update to the latest agent from the public instance as they are released: https://github.com/WPO-Foundation/webpag...sample#L92

My guess is that it is probably an older agent that has issues working with the latest release of Chrome.
