This happened when running on an AWS EC2 instance with the following details
- Instance type = c8g.2xlarge
- AMI name = ubuntu/images/hvm-ssd-gp3/ubuntu-noble-24.04-arm64-server-20250610
- JAVA = OpenJDK Runtime Environment Corretto-24.0.1.9.1 (build 24.0.1+9-FR)
- GCC = gcc (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0
Expected vs. actual behavior
VMX shouldn't crash for nativemem & other events
Reproduction Steps
Create an EC2 instance with the details provided & just do make test
Additional Information/Context
No response
Async-profiler version
latest
