Comment 7 for bug 1355281

Let's try to decrease number of nodes which Astute try to manipulate in same time.

Steps:

- go to master node
- `dockerctl shell astute`
- `yum install -y vi`
- `vi /etc/astute/astuted.conf`
- add "max_nodes_per_call: 7"
- kill astute master to apply settings `ps -ef | grep '[a]stute master' | grep -v grep | awk '{print $2}' | xargs kill`
- `exit`
