<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi,
<br>
<br>
I am trying to run starcluster's loadbalancer to keep only one node running until jobs are submitted to the cluster. I know it's an experimental feature, but I'm wondering if anyone has run into this error before, or has any suggestions. The cluster has been
whittled down to 1 node after a weekend of inactivity, and now it seems that when jobs are submitted to the queue, instead of adding nodes, SGE fails.<br>
<br>
