Продолжения Play удерживают http-потоки
Мы реализовали функцию в нашем веб-приложении, которая обновляет графический интерфейс в ответ на новые события на сервере с помощью продолжений Play, как в приложении для чата. Запустив его на некоторое время в продакшене, мы начали испытывать зависания сервера, а точнее http-коннектор нашего сервера Glassfish перестал принимать новые запросы. Дамп потоков показывает, что все http-потоки из пула потоков http ожидают вызова Play Promises. Наш пул потоков имеет 5 потоков (число по умолчанию), что означает, что есть 5 клиентов, ожидающих уведомления, и сервер не может принять больше http-соединений, пока один из реальных клиентов не закроет свое соединение.
Согласно документации Play по продолжению/приостановке запросов, когда запрос приостанавливается вызовом await(), поток запроса должен быть освобожден. В данном случае этого не происходит.

Я провел некоторое исследование исходного кода Play и не смог найти никаких подсказок. Также мой код кажется правильным, но я не уверен (см. ниже). Я надеюсь, что кто-то может указать мне на то, что я, возможно, делаю неправильно.
Версии:
Play 1.2.3
Glassfish 3.1.1
Исходный код:
public class Sessions extends Controller {
public static void waitFor(Query query, long lastSessionId, List openSessionIds) {
String clientId = request.remoteAddress;
List sessions = query
.with(new UpdatedSessions(lastSessionId, openSessionIds))
.execute();
Logger.info("%s -> Updated sessions since %s + %s: %s", clientId, lastSessionId, openSessionIds, sessions);
while(sessions.isEmpty()) {
List ids = await(MailBox.watch(query, clientId));
Logger.info("%s -> Received ids: %s", clientId, ids);
sessions = query.with(new SessionIds(ids)).execute();
Logger.info("%s -> Queried sessions: %s", clientId, sessions);
}
Logger.info("%s -> Delivering %s", clientId, sessions);
List tiles = Tile.forGates(query.gates());
render(sessions, tiles);
}
}
public class MailBox {
private static List>> promises = Collections.synchronizedList(new ArrayList>>());
public static Future> watch(Query query, String clientId) {
Logger.info("Mailbox.watch(%s, %s)", query, clientId);
Promise> promise = new Promise>();
promises.add(promise);
return promise;
}
public static void put(final long sessionId) {
Logger.info("Mailbox.put(%s): promises=%s", sessionId, promises);
if(promises.isEmpty())
return;
final List>> targets = seizePromises();
new Thread() {
@Override
public void run() {
// It's a list because we will accumulate ids before notifying the waiting clients
List ids = Arrays.asList(sessionId);
Logger.info("Mailbox.put(%s): target=%s", sessionId, targets);
for(Promise> promise : targets)
promise.invoke(ids);
}
}.start();
}
private static List>> seizePromises() {
List>> result = new ArrayList>>();
synchronized (promises) {
result.addAll(promises);
promises.clear();
}
return result;
}
}
