java.lang.StackOverflowError in SAP PO

[Former Member]

Hello Guys,

We are receiving failed messages in SAP PO single stack.

Following are the error details.

Mapping "xyz_mapping" failed to execute: javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: java.lang.StackOverflowError, RuntimeException: java.lang.StackOverflowError, java.lang.StackOverflowError

Transmitting the message to endpoint <local> using connection IDoc_AAE_http://sap.com/xi/XI/System failed, due to: com.sap.aii.af.service.mapping.MappingException: Unexpected exception caught while executing mapping: javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: java.lang.StackOverflowError

Scenario - Message flows from ECC to SFDC through PO for updating order details

Analysis done from our side:

--> We found that order which are failed contains very long text at header level due to which source payload contains very big size and message failed.

--> But after doing further analysis we found that multiple idoc triggered for the same order and some idocs reached successfully to receiver side & some are still in the system error,

--> while executing input payload directly in ESR mapping, same stackoverflow error occurred in production system, but we are not facing this issue in development & quality system

--> one more point for your reference, currently our system upgraded to Support pack 16.

Kindly provide your valuable inputs.

Thanks & Regards,

Hello Riya,

Tell your basis team to increase the Java Heap Size(java memory allocation) in PI.

And also increase the heap size in your system(in control panel) and download ESR save the file and increase the heap size by opening the file in notepad.
