Description

Ambari Metrics Collector grabs almost whole free memory for VSZ just after start.

 free -g

                total       used       free     shared    buffers     cached
Mem:            29         14         15          0          0          4

As you can see free mem is 15GB
AMS Collector process:

ps -u -p 15921 | awk '{print $0}'
