@johnaohara have you seen anything similar? |
|
Which was fixed however |
|
@geoand Does your reproducer fail for master now? (https://github.com/geoand/quarkus-vertx-threads-blocked) |
|
Let me check |
|
Have just re-run against 1.0.0.CR1 and is working as expected |
|
I just ran it my reproducer against master and it worked just fine. |
|
I looks like there is a race condition in |
|
@johnaohara I've simplified my program and can reproduce it in several of my environments. My endpoint: @Path("/hello")
public class ExampleResource {
@GET
@Produces(MediaType.TEXT_PLAIN)
public String hello() {
StringBuffer buffer = new StringBuffer();
try {
Thread.sleep(10);
} catch (InterruptedException e) {
e.printStackTrace();
}
buffer.append("[");
for(int i = 0 ;i <1000;i++ ) {
buffer.append("{\"id\":1,\"name\":\"tom\",\"sex\":\"f\",\"testCode\":\"12345\"},");
}
buffer.append("{\"id\":1,\"name\":\"tom\",\"sex\":\"f\",\"testCode\":\"12345\"} ]");
return buffer.toString();
}
}Run wrk When the wrk is running, the endpoint can be accessed through the browser. source code |

@yuhaibohotmail thanks a lot for the reproducer, I will use it to test a potential fix. |
|
@yuhaibohotmail what hardware are you running on? I am not reproducing the error on my local machine, but will also test in our lab |
|
I can re-create now |
|
@johnaohara Can you reproduce it now？ I tested it in two environments.
|
|
@yuhaibohotmail I have your test running without hanging the application. Now waiting on CI and approval for the PR. Thanks |
|
@yuhaibohotmail #5451 fixes this issue and will be included in the next release. Thank you for your help |
