Hi,
We have a message stuck in AE, we can see the message in RWB with status To Be delivered.
The details says the message successfully put in receive queue and no more detials after that.
This is Exactly once message not EOIO so no othere message is blocking this message. Would there be some othere issue
or any Basis setting that the AFWMessagebean is not picking up this message.
Thanks,
Vinay Mallapu.
Hi Vinay,
As a workaround, you may restart the Java Server in order to reprocess the messages.
If it works, then the problem may be related to insuficient threads. For this ensure the
parameter MaxThreadCount is set to "350" or higher.

Hi Caio,
restarting the Java Server would not fix the issue. Increase the Max. parallel connections would help to fix.
Refer the below blog by Stefen Grube : Deal with stuck EOIO messages
/people/stefan.grube/blog/2006/04/27/how-to-deal-with-stuck-eoio-messages-in-the-xi-30-adapter-framework
Thanks,
Thanks All,
I asked Basis to look into the parameters.
There were many messages in our queues and we started clearing them. Lot of them in To be Delivered status and they are getting processed slowly one by one. Basis is looking at increasing the parameters.
Cancelling the System error messages and rescheduling the To be delivered messages solved the problem.
The message got processed.
But we still need to look at the parameters.
Points awarded to all.
Thanks,
Vinay Mallapu.

Hi Vinay,
The parameters can be chaged from visual administrator or NWA if you dont have access then talk with basis team.
One parameter is messaging.system.queueParallelism.maxReceivers this is in SAP XI AF messaging service
please check http://help.sap.com/saphelp_nw04/helpdata/en/59/25ee41c334c717e10000000a155106/frameset.htm
Other is messaging.connectionDefinition this is in SAP XI AF Core
please check http://help.sap.com/saphelp_nw04/helpdata/en/5c/22ee41c334c717e10000000a155106/content.htm
hope it helps. please be careful in tuning this values as it depends on your message volume in adapter engine and system resources.

francis

Hi Vinay,
you can check the "detail view" in RWB-message monitoring-adapter engine overview ... which will display in which java server node the message has stuck with to be delivered status.
to see messaging system queue for that adapter type check RWB->comp-monirotingg->adapterengine->engine-status->messaging details this gives you the details of worker threads available for message processing for that particular adapter or if they are stuck
also check the below link for troubleshooting
http://help.sap.com/saphelp_nw04/helpdata/EN/49/e3fb40ef74f823e10000000a155106/content.htm
some suggestions like increasing the max parallel connections discussed in below forum might be helpful as well
regards,
francis
