Jboss作为7.1.1EJB 3: ejb池错误

Question

我们在JBoss7.1.1上运行了一个应用程序，并使用了EJB 3。

org.jboss.as.ejb3.pool.strictmax.StrictMaxPool.get(StrictMaxPool.java:109)：JBAS014516:在org.jboss.as.ejb3.component.pool.PooledInstanceInterceptor.processInvocation(PooledInstanceInterceptor.java:47) at org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:288) at org.jboss.as.ejb3.remote.EJBRemoteTransactionPropagatingInterceptor.processInvocation(EJBRemoteTransactionPropagatingInterceptor.java:8 5分钟内没有获得许可( 0) org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:288) at org.jboss.as.ejb3.component.interceptors.CurrentInvocationContextInterceptor.processInvocation(CurrentInvocationContextInterceptor.java :41) org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:288) at org.jboss.as.ejb3.component.interceptors.LoggingInterceptor.processInvocation(LoggingInterceptor.java:59) at org.jboss.invocation.InterceptorContext.proceed(在org.jboss.as.ee.component.NamespaceContextInterceptor.processInvocation(NamespaceContextInterceptor.java:50)，org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:288)，org.jboss.as.ejb3.component.interceptors.AdditionalSetupInterceptor.processInvocation(AdditionalSetupInterceptor.java:32)，org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:288)，org.jboss.as.ee.component。TCCLInterceptor.processInvocation(TCCLInterceptor.java:45) at org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:288) at org.jboss.invocation.ChainedInterceptor.processInvocation(ChainedInterceptor.java:61) at org.jboss.as.ee.component.ViewService$View.invoke(ViewService.java:165) at org.jboss.as.ejb3.remote.LocalEjbReceiver.processInvocation(LocalEjbReceiver.java:179) at org.jboss.ejb.client.EJBClientInvocationContext.sendRequest(EJBClientInvocationContext.java:179) at org.jboss.ejb.client.TransactionInterceptor.handleInvocation(TransactionInterceptor.java:43) at org.jboss.ejb.client.EJBClientInvocationContext.sendRequest(EJBClientInvocationContext.java:181) at org.jboss.ejb.client.ReceiverInterceptor.handleInvocation(ReceiverInterceptor.java:128) at org.jboss.ejb.client.EJBClientInvocationContext.sendRequest(EJBClientInvocationContext.java:181) at org.jboss.ejb.client.EJBInvocationHandler.doInvoke(EJBInvocationHandler.java:136) at org.jboss.ejb.client.EJBInvocationHandler.doInvoke(EJBInvocationHandler.java:121) at org.jboss.ejb.client.EJBInvocationHandler.invoke(EJBInvocationHandler.java:104)

下面是standalone.xml中EJB子系统的配置

我们正在试图排除可能导致此问题的原因，并对其进行修复。

当配置的EJB池耗尽时，就会发生这种情况--这意味着所有EJB当前“正在使用”(=处理)。在EJB中寻找长期运行的调用。在您的情况下，调用时间似乎超过5分钟。
