Also, did you enabled the sampling profiler using the [profiling\_inferred\_spans\_enabled](https://www.elastic.co/guide/en/apm/agent/java/current/config-profiling.html#config-profiling-inferred-spans-enabled) option or did you used the default settings ? ---

> Did you try the suggested solution? - Yes. After trying a few directories I knew to be executable and getting that same message (the default was `/tmp`), I noticed the following in that stack trace: ```auto Caused by: java.lang.UnsatisfiedLinkError: /usr/bin/libasyncProfiler-linux-arm-672c6dfb97228a24cd9de46d11a995ed.so: /usr/bin/libasyncProfiler-linux-arm-672c6dfb97228a24cd9de46d11a995ed.so: wrong ELF class: ELFCLASS32 (Possible cause: can't load ARM .so on a AARCH64 platform) ``` ---

Thanks for reporting this, [async-profiler](https://github.com/jvm-profiling-tools/async-profiler) should support aarch64, thus I've opened [an issue](https://github.com/elastic/apm-agent-java/issues/1439). You can subscribe to it for updates. Also which OS/distribution are you using ? That might be useful to help reproduce it. ---

Also, could you try to use the standalone [async-profiler](https://github.com/jvm-profiling-tools/async-profiler#download) directly to see if that makes a difference ? Trying both `arm` and `musl` variants sounds relevant in this case. ---

@likewhatevs Please download [this snapshot build](https://apm-ci.elastic.co/blue/organizations/jenkins/apm-agent-java%2Fapm-agent-java-mbp/detail/PR-1443/3/artifacts) and see if you can use the sampling profiler on your aarch64 box with it. ---

Better test [this snapshot](https://apm-ci.elastic.co/blue/organizations/jenkins/apm-agent-java%2Fapm-agent-java-mbp/detail/PR-1443/5/pipeline), where I applied a minor change to the OS architecture lookup. ---
