FWIW, we tried to run our job in a rax provider VM (provided by ianw from
his personal account)
and we ran the tempest tests twice, but the OOM did not re-create. Of the 2
runs, one of the run
used the same PYTHONHASHSEED as we had in one of the failed runs, still no
oom.

Jeremy graciously agreed to provide us 2 VMs , one each from rax and
hpcloud provider
to see if provider platform has anything to do with it.

So we plan to run again wtih the VMs given from Jeremy , post which i will
send
next update here.

thanx,
deepak
