OutOfMemoryError during Aruba Inventory Poll - DX NetOps Virtual Network Assurance

Products

• Network Observability
• Virtual Network Assurance

Issue/Introduction

Virtual Network Assurance (VNA) encounters service instability and crashes when processing large-scale Aruba inventory polls.

 

Symptoms:

• VNA process crashes with java.lang.OutOfMemoryError: Java heap space.
• ActiveMQ Artemis logs show paging on the PerformanceUpdateQueue (Error: AMQ222038).
• Increasing VNA_MAX_MEM in standalone.conf only delays the crash but does not resolve the memory growth.
• Heap dumps show millions of LinkedBlockingQueue nodes and large byte[] arrays retained.

Environment

• DX NetOps Virtual Network Assurance 24.3.11
• Aruba Plugin
• Large environments (4,000+ APs / 75,000+ Clients)

Cause

A defect in the Aruba plugin causes inventory and performance messages to be sent individually to the internal message queue. In high-scale environments, the sheer volume of individual messages overwhelms the PerformanceUpdateQueue, causing excessive heap utilization and queue congestion.

Resolution

This issue is a known defect and is addressed via defect DE208995.

 

Fixed in release: Targeted to be fixed in release NetOps 25.4.11 and higher.
