- it passed on other platforms and
- same tests passed when QE ran them.
I was really not sure what was causing this, when Wayne mentioned yesterday that the machine that is hosting a bunch of build sanity VMs were consistently running at 100% CPU. This led me to investigate this a little further and it turns out that while running build 904 (or greater)the memcached process gets to 350-380% of CPU. And pretty much stays that way for the entirety of test suite.
I ran this multiple times on both centos and ubuntu (builds 903 vs 904) and was able to see memcached going crazy with build 904.
