在某个provider突然OOM下线之后，consumer消费端会将对应端口对应的线程池关闭，这是是不可能会导致内存泄露啊。因为我看那个异步任务的超时检测通知也是由这个线程池来执行的。
private static class TimeoutCheckTask implements TimerTask {
private final Long requestID;
TimeoutCheckTask(Long requestID) {
this.requestID = requestID;
}
@Override
public void run(Timeout timeout) {
DefaultFuture future = DefaultFuture.getFuture(requestID);
if (future == null || future.isDone()) {
return;
}
if (future.getExecutor() != null) {
future.getExecutor().execute(() -> notifyTimeout(future));
} else {
notifyTimeout(future);
}
}
private void notifyTimeout(DefaultFuture future) {
// create exception response.
Response timeoutResponse = new Response(future.getId());
// set timeout status.
timeoutResponse.setStatus(future.isSent() ?
Response.SERVER_TIMEOUT : Response.CLIENT_TIMEOUT);
timeoutResponse.setErrorMessage(future.getTimeoutMessage(true));
// handle response.
DefaultFuture.received(future.getChannel(), timeoutResponse,
true);
}
}
