VNA is running OOM - Performance problem with Meraki Plugin

Products

• CA Virtual Network Assurance

Issue/Introduction

VNA 21.2.1 is running OOM.  We have configured VNA to use 16GB - we have less than 1000 devices.  Why is it running OOM?

Cause

Rate Limit Issue

Environment

Release : 20.2

Component : Virtual Network Assurance For CA Spectrum

Resolution

There was a "rate limit" issue that was causing excessive memory consumption.

There is a fix for the rate limit problem in NetOpse VNA  version 21.2.3 and above.

Also, if not needed, in the VNA Plugin config disable the below entities to overcome the rate limit issue:

SSIDs
Policies and firewall rules

Since then we haven't seen any out of memory issues.
