I was hoping that someone might have some ideas on a problem we have experienced a handful of times running galaxy on our local cluster.
Occasionally we experience some communication timeouts between out cluster head node and a compute node which will self heal. However, this in turn will hang galaxy. Below you will see output from our galaxy log file. When the ERROR happens (which is not often) it consistently seems to hang galaxy. We have to kill it off and restart it. We are running galaxy as a single PID at this time (we are still just testing it out, etc) and it is running on our head node (which we plan to move off of in the future).

Has anyone else experienced this or have some ideas on how we can further debug to figure out why galaxy hangs?
