Unable to download JFR recordings larger than 10MB via Tunnel Server #3034
Description
- I have searched the issues of this repository and believe that this is not a duplicate.
Environment
- Arthas version: 4.0.5
- Operating System version: Ubuntu 24.04 LTS
- Java version of target JVM: 21.0.7
- Java version of JVM used to attach: 21.0.7
Preconditions / Setup
- Arthas is attached to the application as a Java agent and connected to the tunnel-server.
- The Arthas Web Console is used to start JFR profiling of the application.
- After profiling finishes, the generated recording is listed under Outputs.
Steps to reproduce this issue
- In the Web Console, click Download for a recording whose size exceeds 10 MB.
- Observe the downloaded file.
Expected Result
The full .jfr file is downloaded intact, regardless of size.
Actual Result
• Recordings ≤ 10 MB download correctly.
• Recordings > 10 MB download as a small file that contains only the text:
error

Questions
- Is the 10 MB ceiling intentional/expected?
- If intentional, is there a recommended work-around to download JFR files larger than 10 MB via tunnel-server for those with no direct access to production system other than the web-console?
Thanks for your help!
