> Reporter: Andrew Onischuk

> Fix For: 2.0.0

> I was performing RU on weekend and left cluster running to finalize it later.
> So cluster was running unattended for 2 days, and ambari-agent died due to out
> of memory. Agents on other nodes are running well.
> Node has 8gb of ram, does not look like memory exhausted (unless agent needs
> more then 1100 mb of ram)
