The error "HTTP Status 400 – Bad Request" may appear when a task for a large number of computers is triggered from Deep Security Manager (DSM) console.
This is a product limitation, which may happen when triggering a task such as the following:
- Upgrade Agent Software
- Assign Policy
- Assign Asset Value
- Assign Relay Group
To prevent the issue, do not select more than 300 computers at once when you trigger any job from the Deep Security Manager.
