The XML parser does not like the output of "qhost -xml". (We changed some minor XML output code in Grid Scheduler recently,
but as you have encountered this before in earlier versions, looks like our changes are not the cause of this issue.)
I just started a 1 node cluster and let the loadbalancer add another node, and it all seemed to work fine...from the error message
in your email, qhost exited with 1, and a number of things can cause qhost to exit with code 1.
Can you run from the interactive shell the following command on one of the nodes on EC2 when you encounter this problem
again??
% qhost -xml
And then send us the output. It can be an issue related to how the XML is generated in Grid Engine/Grid Scheduler, or it can be
something else in the XML parser.

Subject: [StarCluster] loadbalance error
Hi all,
I was running loadbalance. After a while, I got the following error. Can someone shed some light on this? This happened before with earlier versions of Starcluster as well.
>>> Loading full job history
!!! ERROR - command 'source /etc/profile && qhost -xml' failed with status 1
