Get "Device is offline" when simultaneously sending two requests for a same CPE

The case is two requests would be simultaneously sent for a same CPE.
Two NBI workers simultaneously handle the two requests independently. Each worker gets the chance to send connection request, the quicker one successfully gets response from CPE and establish session with CPE. But the slower one can’t get response thus leads to failure reason “Device is offline” is returned, however CPE is up at that time.
Is there a way in GenieACS to handle this situation?
