Work Process stuck in sequential search

Hi ,

We are running a program in background in pre-production system(Data for this system is refreshed just last week) and i is taking very long.When i look in SM50 i can see a work process stuck 'Sequential Read of DB DFKKOP'.

But the same program runs fine in production without any issues.

Can anyone give a hint or suggestion what could be the issue.

Cheers,
