<p style="margin-top: 0px; margin-bottom: 0px;">Hi All,​<br>
</p>
<p style="margin-top: 0px; margin-bottom: 0px;"><br>
</p>
<p style="margin-top: 0px; margin-bottom: 0px;">I starting running into trouble a few days ago with my Starcluster instances running in us-west-2b (Oregon) where after a day or two (most likely after the load balancer attempts to add nodes to accommodate jobs)
all interaction with the cluster via starclusters management commands results in a "!!! ERROR - instance i-8ac59480 has no alias" error message. As far I know nothing has changed on my end. <br>
</p>
<p style="margin-top: 0px; margin-bottom: 0px;"><br>
</p>
<p style="margin-top: 0px; margin-bottom: 0px;">Fresh starcluster instances were successfully relaunched using the most current release only to have them break again with the same error message. Trolling the starcluster mailing list archives resulted in a thread
from 2013 that suggested that AWS made some temporary changes in the way userdata was handled in some regions that eventually resolved itself. <a href="http://star.mit.edu/cluster/mlarchives/1985.html" id="LPlnk655997">http://star.mit.edu/cluster/mlarchives/1985.html</a></p>
