Hello,
In our environment, we have a system that connects to the mq server, gets messages, processes them and saves data in ms sql db. We want all it go inside a distributed transaction. As a coordinator, we use MSDTC.
In our code, we open TransactionScope, create a connection,session,destination,consumer and then we receive a message. We do it all the time, 5 times a second or so. However, after some time of running, we get an exception:
| Code: |
XMS attempted to close a WebSphere MQ destination, but encountered an error. The destination might already be closed, or another thread may be performing an MQGET while close() is called.
Use the linked exception to determine the cause of this error. You may be able to perform the close() later.
at IBM.XMS.Client.WMQ.WmqMessageConsumer.CheckNmqiCallSuccess(String messageid, String insert, String insertKey, Int32 completionCode, Int32 reason, NmqiEnvironment environment, String probeid, WmqCommonConnection commonConnection, Hconn hconn)
at IBM.XMS.Client.WMQ.WmqConsumerShadow.Close()
at IBM.XMS.Client.WMQ.WmqMessageConsumer.Close()
at IBM.XMS.Client.Impl.XmsMessageConsumerImpl.Close()
at IBM.XMS.Client.Impl.XmsMessageConsumerImpl.Dispose()
Linked Exception : CompCode: 2, Reason: 6109

We don't know what is going on, because we don't use threading here. Can anyone help ? |

So what does this yield when you look:

I've checked the reason, but it doesn't make much sense for me. It says
| Quote: |
| The connection reference is null. A connection to an ImqQueueManager object is required |
which doesn't make sense for me, because I get the exception when I'm trying to dispose the consumer. I was able to receive a message and then when I want to clean up my connection disappears ? |

If you believe you do still have a connection reference at the time your application is trying to close the consumer (which must have a connection reference in order to be used) then this may be worth reporting via a PMR.
