Hey Tom & Everett,

I experienced this regularly on the old Rackspace.

The problem for me was that Rackspace API often reports the node as pending
even after it has booted up. Due to the way my code was set up I was
polling port 22 myself to see when the server was set up rather than using
jclouds blocking methods. I then went on to use
ComputeService.runScriptOnNode() which, from my understanding, checks the
API to see the status of the server. Since it was sometimes still pending
and not running/active it could fail.

If you aren't using the jclouds ways of blocking until a server comes up,
or if you aren't polling it's state from the API then this could be the
reason. I haven't actually upgraded to next gen yet so I could be barking
up the wrong tree of course!

I fixed this by polling the API and then trying to run commands. This was
implemented with a Predicate to check if the NodeState was Running and
using that within a RetryablePredicate (a super awesome jclouds class). If
you think it will help you I can dig out the code for this - just ask!

Hope this can shed some light,

Chris
