WF-BATCH memory consumption keeps growing

Hi,

I am faced with a unique issue in a Netweaver ABAP system.

In SM04, i see two lines for user WF-BATCH (used for all workflow and background jobs).

Each line item shows over 1 GB memory consumed and this number keeps growing every day.

On looking at memory details, it seems the roll area is growing.

I don't know what data is inside that memory . We don't have any long running background jobs or dialog processes.

Is there any way to find out what's going on ?. I already tried basic tracing, but that did not help much.

Regards,

Jeron
