Blocking Read Timeout in Request API REST

[Rui Alves]

Hi,

I have this exception: java.io.IOException: Blocking read timeout

It happens when a GET web service is used with data of considerable size.

Can anyone help ?

Regards,

Rui

Hi Rui,

do you have some reproducing app? Do you mean, that the GET is returning huge data?

I tried it just now and was able to get 2 GB:

@Path("sample")
public class SampleResource {
    @GET
    @Path("huge")
    public Response messageHuge(@QueryParam("count") @DefaultValue("1000") int count) {
        return Response.ok("x".repeat(count)).build();
    }
}

curl http://localhost:8080/HugeGet/rest/sample/huge?count=2000000000

I tried also waiting for 15 minutes and I didn't get any timeout.

Do you have some more info, e.g. stacktrace?

Thank you,

Petr

Hi, Peter,

My apologies, but I’ve been on holidays and away from the computer.

 little of the stacktrace:

I suspect he gets a lot of requests and somehow doesn’t respond. I explained it wrong, the problem is not so much the size of the data that go in the POST, but the number of requests at the same time.
