Looping message in Adapter Engine

Hello!

We had a message  which went fine in mapping (IDOC -> proxy) / integration engine (check flags in sxi_monitor) but stopped in Adapter Engine with status "To be delivered". No jammed queues or anything. It didnt help to restart the message, it was just looping. We had to restart one of the PXI-servers and after that it worked succesfully.

Any ideas what could have caused this or how I can fault-trace / debug this?!

Hi Stefan,

To be Delivered can happen because of two reasons:

1. PI Performance due to sudden heavy loads OR

2. in this case Receiver system Perfomance may be the case ..

pls check once with the receiver system performance .. and also the note suggested above(1623356) which mentions thread increase for that particular adapter type.

I hope this will help..

Thanks,

Hi All,

This is a system issue and it can't be resolved in any way.
This is probably the issue within Runtime threads and it can be resolved only by restarting the PI server. We had a same issue in PO 7.4 where there were couple of messages were going to TobeDelivered status amd Delivering status without any prior error messages. After all the required analysis, SAP had to add a new patch and then the issue got resolved.

Thanks,

Hi Venkat,

Thanks for this input. So am I understanding you correct if this is patched in newer release of PI?

Is there a note on this or something?

Hi Stefan,

The only way to debug or trace it now would be to have a look in your developer logs. Have a look on NWA under logs and filter on the time it happened. If something was wrong it should appear there.

One of the java service might have gone for a loop and the message got stuck. Its rarely happens but you never know.

Hope it helps,

Hi,

thanks for your reply. I have looked in NWA but I can't find anything that implies that something has looped or been retried many times. It's not easy, I'm not even knowing what I'm looking for

Hi,

Yeah this is a difficult issue to find and even more difficult to resolve. But lets hope for the best.

It is not possible to replicate this issue?
