Concurrent Managers generating huge archives in EBS R12.1.3

Hi Folks,

The archives are generating for every 3 minutes in one of our EBS R12.1.3 environment

When we reviewed the session details which are causing this, all the details shown in PROGRAM column are of concurrent managers.

Verified all the debug options and could not able to figure out the reason.

Any help in troubleshooting this is highly appreciated.
