Bug Report

What version of Kubernetes are you using?

Client Version: v1.28.1 Server Version: v1.23.17 What version of Chaos Mesh are you using?

2.5.1 What did you do? / Minimal Reproducible Example

Create a JVMChaos with latency & Exception, both select the port for non-using port. What i have checked

• [x] 1. Linux Kernel Version 5.15.0-69-generic
• [x] 2. Check byteman-jar, byteman-helper-jar, chaos-agent.jar exist in application pods
• [x] 3. Java 8
• [x] 4. curl 127.0.0.1:9277 failed (i select 9277 as my port configuration) In my understanding, with the port configuration i should select a port which is not been used?
• [ ] 5. Should i check namespace contains the label for Admission Webhook?

What did you see instead? On chaos mesh UI the experiments are both in Injecting Status. Both shows Failed to apply chaos: rpc error: code = Unknown desc = exit status 1 . Application Logs: Latency Experiment Agent failed to start!

This should be an error in the execution of your bminstall.sh script; please check the execution result of bminstall.sh.

I would take a look about the JVMChaos compatibility, we could continue discussing in https://github.com/chaos-mesh/chaos-mesh/discussions/4204
