Rxjava2 OutOfMemoryError

Question

我经常收到OutOfMemory错误。

示例代码：

Flowable.fromIterable(req.getAllClaims()).filter(Objects::nonNull)
            .flatMap(data -> {
                ClaimStatusCollector collector = statsCollector.get(data.getName());
                collector.setVehicleHelper(vehicleHelper);
                collector.setMedicalHelper(medicalHelper);
                return Flowable.fromCallable(() -> collector.verifyStatus(data)
                        );
            }, 5)
            .blockingIterable().forEach(data -> {
                claims.add(data.blockingFirst());
            });

VehicleClaimStatusCollector.java 
@Override
public Flowable<Claim> verifyStatus(Claim claim)
{
    return Flowable.create(emitter -> {
        try
        {
            //external http call
            emitter.onNext(claim);
        }
        catch (Exception e)
        {
            emitter.onNext(claim);
        }
        emitter.onComplete();
    }, BackpressureStrategy.BUFFER);

}

MedicalClaimStatusCollector.java 
@Override
public Flowable<Claim> verifyStatus(Claim claim)
{
    return Flowable.create(emitter -> {
        try
        {
            //external http call
            emitter.onNext(claim);
        }
        catch (Exception e)
        {
            emitter.onNext(claim);
        }
        emitter.onComplete();
    }, BackpressureStrategy.BUFFER);

}

很明显，我们从外部http请求中获取套接字异常。我还在球衣客户端中设置了readtimeout。所有线程都挂在那里，并抛出内存不足错误。

有人可以帮我吗？
