在OpenShift上重新啓動WildFly時出現內存不足錯誤

我在OpenShift上遇到了WildFly AS的問題。當我嘗試在服務器上部署WAR時，我不斷收到以下異常。在OpenShift上重新啓動WildFly時出現內存不足錯誤

我不知道它的相關但我認爲錯誤開始時，我添加了休眠到我的應用程序。這裏是hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> 
<hibernate-configuration> 
    <session-factory> 

     <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> 
     <property name="connection.datasource">java:comp/env/jdbc/MyDataSource</property> 
     <property name="hibernate.current_session_context_class">thread</property> 

     <!-- GENERAL CONFIGURATION --> 
     <property name="connection.pool_size">1</property> 
     <property name="hibernate.show_sql">false</property> 
     <property name="hibernate.connection.release_mode">after_statement</property> 
     <property name="hibernate.connection.autocommit">false</property> 
     <property name="hibernate.connection.defaultAutoCommit">false</property> 

     <!-- DB MAPING --> 

    </session-factory> 
</hibernate-configuration>

我HibernateUtil.java：

import org.hibernate.SessionFactory; 
import org.hibernate.boot.registry.StandardServiceRegistryBuilder; 
import org.hibernate.cfg.Configuration; 
import org.hibernate.service.ServiceRegistry; 

public class HibernateUtil { 
    private static SessionFactory sessionFactory; 

    public static SessionFactory getSessionFactory() { 

     if (sessionFactory == null) { 
      // loads configuration and mappings 
      Configuration configuration = new Configuration().configure(); 
      ServiceRegistry serviceRegistry 
       = new StandardServiceRegistryBuilder() 
        .applySettings(configuration.getProperties()).build(); 

      // builds a session factory from the service registry 
      sessionFactory = configuration.buildSessionFactory(serviceRegistry);   
     } 

     return sessionFactory; 
    } 
}

我DaoImpl我使用登錄名和部分：

public User login(String username, String password) { 

     User result = null; 

     Session session = HibernateUtil.getSessionFactory().openSession(); 
     try { 
      String sql = "select s from User s where username=:username and password=password(:password)"; 
      Query query = session.createQuery(sql); 
      query.setString("username", username); 
      query.setString("password", password); 
      result = (User) query.uniqueResult(); 
     } 
     finally { 
      session.close(); 
     } 

     return result; 
    }

我不是100％舒爾其問題休眠，因爲我通過SSH連接刪除所有在wildfly/standalone/deployments/和重新啓動應用程序，但我仍然遇到錯誤，當我執行gear start命令。

小齒輪具有250個線程的線程限制，儘量限制線程＃用於消息傳遞服務50（或者甚至嘗試20取決於應用）。該配置位於standalone.xml文件中。

如：

<subsystem xmlns="urn:jboss:domain:messaging:2.0"> 
    <hornetq-server> 
     <thread-pool-max-size>50</thread-pool-max-size> 
     <scheduled-thread-pool-max-size>50</scheduled-thread-pool-max-size>  

     <!-- ... --> 

    </hornetq-server> 
</subsystem>

我希望這幫助。

如果我不需要消息，我可以設置池大小爲1？或者它是由OpenShift用戶？ – Kiki

@Kiki如果你不需要消息，您可以從配置中移除消息子系統（'standalone.xml'' '）。 –

看看這個thread。

我發現我不得不禁用不僅消息也clustering.jgroups。不過，我之後偶爾會遇到OutOfMemoryError。我限制了數據庫連接池。默認情況下它是無限的。

可悲的是，這是不夠的，我還去了與

管理執行人服務最大線程數25 - > 15
JCA：2.0螺紋50 - > 20

仍有沒有線程爲phpMyAdmin :(沮喪...
