SYSTEM_NO_ROLL

Hi,

Could anyone help me with this query.

I am getting the dump SYSTEM_NO_ROLL while processing a back ground job which triggers asynchronous RFCs while doing parallel processing. I understand this is related to memory not available but I am not able to understand how my program is using up large memory space.

There is one large table which has 400,000 data which is processed in block of 50000 processing 30 records at a time. All the internal tables are refreshed and there is no chance that garbage data is building up somewhere in the program.

Can I have some insight on how to get hold of the issue and resolve it.

Thanks..

In addition to REFRESHing the internal tables, also FREE them.

So your main program with 400,000 records triggered 8 tasks of 50,000 records simultaneously ? (so at this step you consume space for 800,000 records + temporaty space for the end of task processing) then your 8 tasks process records by package of 30?

So no parallelism?

Hi Raymond,

The records are processed in parallel after initial data selection. My issue is resolved. I had used the function group related to RFC for another technical object. It was causing the memory leak.

Hi Swati,

I had checked and read through most of the SDN posts before posting my query. I resolved the issue but none of the existing SDN posts were helpful.

Thanks,

Ritesh
