Sebastian Violet commented on CXF-8946:
---------------------------------------
My apologies for not giving the command to run the program.
{code:bash}
mvn clean install spring-boot:run{code}
You can have a simple Express js application that serves the request of the
JAX-RS client. In may case, it looks something like so:
{code:javascript}
const express = require('express');
const app = express();
const port = 9899;
const bodyParser = require("body-parser");
app.use(bodyParser.urlencoded({ extended: true }));
app.post('/status', (req, res) => {
res.setHeader('Content-Type', 'application/json');
// res.send(501, '{"status": "bad"}');
// res.send(404, '{"status": "bad"}');
// res.send(200, '{"status": "ok"}');
res.send(204, '');
});
var server = app.listen(port, () => {
console.log(`Example app listening at http://localhost:${port}`);
})
server.keepAliveTimeout = 1200 * 1000;
{code}
And the script to run the load against the SpringBoot app is here:
[^call_mem_leak.sh]
You can execute it like so:
{code:java}
./call_mem_leak.sh -c 50000 {code}
> HttpClient in CXF causing memory leak
> -------------------------------------

> Key: CXF-8946
> URL: https://issues.apache.org/jira/browse/CXF-8946
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 4.0.3
> Reporter: Sebastian Violet
> Priority: Major
> Attachments: CXF-HTTPClient-MemoryLeak.zip, Screenshot 2023-10-19 at
> 2.29.56 PM.png, call_mem_leak.sh, java_pid17394.hprof.zip,
> java_pid17394_Leak_Suspects.zip, java_pid91652.0001.hprof.zip,
> java_pid91652.0001_Leak_Suspects.zip, memory-leak-demo.zip
>
>
> When processing requests using the JAX RS client which used the new
> HttpClient, there is a memory leak.
> We found this when running it in spring boot using
> {code:java}
> @Async{code}
>
> I have tried to reproduce it using the attached code, and it seems to work
> with a low heap size.
>
> You can execute the code like so:
> {code:java}
> mvn compile exec:exec{code}
