SAP VM_STACK_TRACE: java.lang.OutOfMemoryError:Failed to allocate 546152 bytes when copying a shared closure

Dear experts,

we use a customer report to create a large amount of invoices at once. During out last invoice run, the system ended the processing with a shortdump VM_STACK_TRACE.

After we've reported it and get a parameter recommendation from SAP we've tried it again. Result is the same shortdump.

The recommended parameters were:

vmcj/option/maxJavaHeap = 1024
vmcj/option/percentageYoungGen = 10
vmcj/option/percentageMinOldGen = 5

An extract from the VM_STACK_TRACE:

Do you have any ideas for the correct parametrization?

Our problem is that we can't test our invoice run. So we have to test it on a productive run which executed twice a month.

Thanks in advance.

Best regards,

Paul

Hello Paul,

your reported issue are in a completely in the wrong area. Please copy the actual issue to the VMC community (sorry, I'm technical not able to copy the issue) and close the actual issue. In the CRM Service we are deals with  CRM Service specific application question/problems and we usually are not familiar with  VMC (or other Basic topics).

Thank you for understanding and cooperation.

Best Regards

Gerhard
