Unexpected Message Exception in BizTalk during WCF call

Question

Getting following exception when calling a WCF service from BizTalk ORchestration.

 

xlang/s engine event log entry: Uncaught exception (see the 'inner exception' below) has suspended an instance of service 'Processes.AribaRequisitionPush_1Client(9792f23e-1913-5f83-1851-e5a2b706da2e)'.
The service instance will remain suspended until administratively resumed or terminated.
If resumed the instance will continue from its last persisted state and may re-throw the same unexpected exception.

Answer 1

Seems like you are getting a fault message from the service. Have you handled those in your process of calling the web service. I would suggest create a send port with filter messagetype = http://schemas.xmlsoap.org/soap/envelope/#Fault and see what the fault is. Check this for Fault handling in WCF Services. Check this blog post too has some examples.

I have setup the filter and getting the following error.

 

A response message sent to adapter "WCF-BasicHttp" on Receive Location: "WcfSendPort_AribaRequisitionPush_BasicHttpBinding_IRequisitionPushService" with URI:"http://10.163.111.98/ARCServices/AribaRequisitionPush.svc" is suspended.

Error details: The message found multiple request response subscriptions. A message can only be routed to a single request response subscription.

MessageId: {DFEAD193-637E-4492-9267-600B53561F76}

InstanceID: {05215344-3205-4088-BEDC-72680875568E}

 

I have checked that I am not having mulitple request response ports on my orchestration but still getting this eror?

Please help

Answer 3

Hi, 

Can you share the filters that you have set, this error reminds me of a hotfix for a problem in BizTalk Server 2006, which version of BizTalk are you using? Check this blog post for a similar issue. The hotfix is available here.

Also at what point of time you are getting this error. For subscriptions you should check with a query from the admin console too.

Hi Bali,

 

I am using BizTalk Server 2010 and I don't think so hotfix is required for it because there is checkbox available in the host instance settings to enable multiple request response mechanism. I did that but didn't work. I am setting followng filters.

 

messagetype = http://schemas.xmlsoap.org/soap/envelope/#Fault

I also checked the active subsription from console but unable to find any other subscription. Similarly I have double check the Orchestration as well.

I am still getting the same error. Please provide me some solution to it. I have wasted the whole day to get rid of this error but no success. It is really hurting my deadline. Please help me out....

Thanks,

Tahir

 

 

Answer 5

Hi Tahir,

In case it's BTS 2010 after you change the setting on the host , you should restart the host instance, if you haven't already done so. Also make sure that you set the property on the host instance the port is running under. 

HTH.

Answer 6

What is HTH property?

I have done that but now again I am getting the basic error.

 

xlang/s engine event log entry: Uncaught exception (see the 'inner exception' below) has suspended an instance of service 'Processes.AribaRequisitionPush_1Client(dc764d67-9af2-af33-da35-ec633fb1c3ba)'.

The service instance will remain suspended until administratively resumed or terminated.

If resumed the instance will continue from its last persisted state and may re-throw the same unexpected exception.

Answer 7

Well :( .. my bad HTH was hope this helps. I have seen this error earlier, check this blog post, will give you an insight of what this error is.  So basically on this response from the service you will either get the correct response or the fault message, you will have to handle both in your process.

Answer 8

Error details: The message found multiple request response subscriptions. A message can only be routed to a single request response subscription.

MessageId: {DFEAD193-637E-4492-9267-600B53561F76}

InstanceID: {05215344-3205-4088-BEDC-72680875568E}

 

This error is because you have deployed the same schema twice. Please check your admin console under "All Artifacts".

 

Thanks
