Too many Workflow Background Processes running

Hello Guys,

Every month I create a report to submit to my higher authorities. In the report there is a section called "Total Concurrent Requests Processed".

I use the query :

select count(*) from FND_CONCURRENT_REQUESTS where trunc(request_date) between '01-Aug-2015' and '31-Aug-2015' order by request_date desc;

to find the number out. I only need to report this number.

But since 2 months, I have been finding a very huge number of concurrent requests being run in my environment. Here are the  approx. stats of last FOUR Months.

MAY      JUNE     JULY       AUGUST

57000    45000    172000    1318000

I investigated this issue and found out that the "Workflow Background Process" is the Program that has been running on a huge number of times out of this. I'm not sure why.
