Symptoms

In a VCP 12.1.3.8 Instance (Centralized VCP Environment, using ATP based on planning output):
ATP is unavailable when running the 24x7 ATP plan.

When running ATP with 'Enable 24x7 ATP' = 'Yes , purge current plan after switch plan', get the 'ATP is currently not available due to planned down time' error message for a minute or two.  It seems to correspond to the time that these programs are running (under the ATP plan):

Need to know what can be done so that one can minimize ATP downtime while running ATP plans.

-- Navigation path, on how to consistently reproduce the issue.
When running ATP plan with 24x7 enabled, get the 'ATP unavailable' message for a minute or two.

-- Business Impact
The ATP downtime causes problems in Order Management and requires extra work to fix issues after the fact.  The expectation is that ATP will be available when running the ATP plan with 24x7 enabled. Currently, it is down for a couple of minutes every time when running the ATP plan.
