The original bug was for SLSB, but it still affects MDBs. The lookup occurs normally. I know that a message which has been delivered to the server running the MDB will time out after 10 seconds if there is no instance in the bean pool to

My assumption up to this point is that the MDB requests messages from the broker in the quantity of only when it no longer has any messages to process. Need access to an account?If your company has an existing Red Hat account, your organization administrator can grant you access. It has been detected that the MessageSucker component which sucks messages from one node to another has not had its password changed from the installation default. When a batch of JMS messages is delivered to an MDB in the quantity of the prefetch each are assigned an instance from this pool and are delivered to that instance

Any other suggestions will be appreciated.Happy New Year! http://computerhelpdev.com/failed-to/failed-to-acquire-gss-api-credentials.php Setting maxSessions to 5 resolves the issue as the broker will only attempt to deliver 5 messages at a time (remembering we also have prefetch set to 0).

so my question is, how can this error occur when messages are being polled instead of batched? If you have any questions, please contact customer service. Hi Guys, I see that this problem's come up a few times in the past but our scenario is different so I'll raise it again.

PBnew MDB:package com.xxxx.wab.mdb.ssim; import java.util.ArrayList; import javax.ejb.ActivationConfigProperty; import javax.ejb.MessageDriven; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.ObjectMessage; import javax.persistence.EntityManager; import javax.persistence.PersistenceContext; import com.xxxx.wab.dao.MasterFlightDAO; import com.xxxx.wab.dao.SubscriberDAO; import com.xxxx.wab.dto.SsimRsp; import com.xxxx.wab.service.SsimService; import com.xxxx.wab.ssim.SsimFlight;

Some quick algebra reveals that this will occurs, roughly speaking, when timeout < (prefetch x onMessageTime) / maxSize This assumes that messages are distributed instantaneously, and each onMessage takes the same The slow queue threw the following exception 5 times during the period of time both queues were loaded with messages. In the PoolClass annotation, we are using a maxSize of 1 in an attempt to force processing of messages in the order they were loaded on the queue.
