RAM Usage very high and increasing

Products

• CA Privileged Access Manager (PAM)

Issue/Introduction

Very high PAM usage is observed in one instance (above 80%)
Upon reboot it comes back after some time, and multiple reboots do not help

 

Environment

Release : 4.x

Component :

Cause

There are several processes, such as cspm, mysql, jboss and the utility appliance containerd ones which naturally take quite a bit of memory, even if the system is not in production
If the appliance is being used in production memory usage may increase
This is the reason why the documentation recommends at least 16 Gbyte RAM, with 64 Gbyte strongly advised for a production appliance
If the appliance has too little RAM, such as 16 Gbyte, memory may be at high utilization all the time

Resolution

It is recommended to increase the memory available for the CA PAM virtual machine to 64 Gbyte
With that memory utilization will decrease under normal operation to about 30%

With 64Gb the memory usage is now 30%
