Description Stephanie Lewis 2012-05-29 03:03:25 PDT
The WebKit 2 bots are flaky because the WebProcess is often killed due to being unresponsive.  I think this probably has to due with how many processes are running in parallel and how heavy the load is on the machines.  

There are some tests that crash more often than others, but it is usually different tests every time.

The data is confused by the fact that some crashes are legitimate but the machine was under enough load that the crash wasn't written out in time.  See https://bugs.webkit.org/show_bug.cgi?id=87717 and https://bugs.webkit.org/show_bug.cgi?id=87714

Blind attempt to reduce flakiness.  We need to investigate the root cause.

I'm not entirely sure if there isn't some undocumented magic in how these numbers relate to each other, but seems fine to try this.
