Occasional mobile failures

[sjernigan]

Config: Physical window 7 machine running website, desktop wptdriver agent, url blast, and wpt_agent for a connected MotoE

When running mobile test, I occasionally (say a third of the time) get failures that I haven't seen on the public instances. The failures sometimes result in 'Data is missing" messages in the test results and other times have the command that timed out.

Below are a few of the stack traces/exceptions I have seen. The desktop tests seem to work fine. Any suggestions on things I could try to diagnose/resolve the problems.

Looks like there is no ipfw_config batch file for windoze. I added a dummy one to get around this for the time. My connection speed is currently fixed by the access point anyhow.

[pmeenan]

Are you running the agent from 2.15 or 2.14? There were a bunch of bugs fixed in 2.15 for the mobile agent where it shouldn't try to use ipfw if it isn't configured (and to bypass ipfw you need to define connectivity=blah in locations.ini).
