load balancer stopped working?

I noticed that my load balancer stopped working -- specifically, it has
stopped deleting unnecessary nodes. It's been running fine for about three
I have a small T2 micro instance loadbalancing a cluster of M3.xlarge. The
cluster is running Ubuntu 14.04 using the shared 14.0. AMI ami-38b99850.
The loadbalancer process is still running (started with nohup CMD &, where
CMD is the loadbalancer command below):
ubuntu_at_ip-10-0-0-20:~$ ps -ef | grep load
ubuntu 11784 11730 0 15:04 pts/1 00:00:00 grep --color=auto load
ubuntu 19493 1 0 Apr26 ? 01:25:03
/opt/venv/python2_venv/bin/python /opt/venv/python2_venv/bin/starcluster -c
/home/ubuntu/.starcluster/config loadbalance -n 1 -m 20 -w 300 dragon-1.3.0
Queue has been empty for several days.

However, there are about 8 nodes that have been running over the weekend
and are not being killed despite -n 1. If anyone has any guesses as to why
the loadbalancer might stop working please let me know so I can prevent
this from happening in the future.
