Unable to open interface due to memory circuit breaker

Memory Circuit Breaker occurs due to poor interface design with resource-intensive operations. The solution is to open the interface during downtime when system resources are available, then optimize it by creating sub-interfaces to break down large components, eliminating unnecessary record/CDT calls on form load.
The root issue is loading too much data or running complex expressions during interface initialization, so restructure the interface to call expensive operations only when needed rather than on interface load.
Temporary workaround is to restart the server.

you can go through the below URL, you may find something about it.

One thing you can do is instead of opening the interface, from the designer select the interface and check its precedents. Then open few precedents which you feel have data queries in it happening or have heavy form/data intensive logics. Comment out the code for them. Once you do this then the main interface will have less load and you will be able to access it. Later you can uncomment the other rules once you identify and fix the code causing this error
