私は、あるソースからデータを取得し、それをMongoDBにアップアップするアプリケーションを持っています。時々引っ張っプロセスは多くの時間がかかり、アプリは以下の例外をMongoDBのために行をプッシュしようとするとタイムアウトの問題におそらく発生しますMongoDB：java.lang.IllegalStateException：状態はopenであるべきです：

今そこはMongoCollectionクラスのラッパーは、各MongoExceptionのためということで、 mongoClientをリロードするjava.lang.IllegalStateExceptionスロー
@Override
public UpdateResult updateOne(Bson filter, Bson update,
UpdateOptions updateOptions) {
UpdateResult retVal = null;
final ExceptionHelper ex = new ExceptionHelper(CAConstants.RETRIES, ErrorType.ERROR, true);
boolean isDone = false;
while (!isDone) {
try {
retVal = proxied.updateOne(filter, update, updateOptions);
isDone = true;
} catch (final MongoException | IllegalStateException e) {
ex.logIfZero("Failed to launch MongoDB operation", e);
if (ex.lastTry()) {
isDone = true;
Log.error("Failed to launch MongoDB operation.", e);
} else {
Log.error("[MDB] Going to update mongo instance due to exception", e);
db = MongoDBFactory.getUpdatedMongoDBInstance();
setCollection();
}
}
}
return retVal;
}
試行のために：
if (mongoClient != null) {
try {
mongoClient.close();
} catch (Exception e) {
Log.error("Mongo client throws exception while closing connection", e);
}
...
mongoClient = new MongoClient(servers, Arrays.asList(credential),
new MongoClientOptions.Builder()
.requiredReplicaSetName(REPLICASET_NAME)
.connectTimeout(0)
.connectionsPerHost(CONNECTION_PER_HOST)
.cursorFinalizerEnabled(false)
.build());
db = mongoClient.getDatabase(database);
しかし、mongoClientが後方に更新されたときER "com.mongodb.MongoSocketReadException：途中でストリームの終わりに達した" ことがで失敗します。私は3.2.9のverにMongoDBを使用して...

この質問をmongodb-userグループ（https://groups.google.com/forum/#!topic/mongodb-user/hhoFxnSplfI）に投稿したことに気がつきました。ここで、RossはあなたにJiraのフォローアップを依頼しました問題。 Jiraでレポートを提出するか、タイムアウトエラーの解決策を見つけましたか？ 「引き上げに時間がかかる」と、どれくらいの期間ですか？ – Stennie
こんにちはStennie、プルプロセスは1時間以上かかることがあります。ポイントは、異なるテーブルからデータを1つずつ取り出すことです。だから、私たちはそれを制御しない... – EVG
