Application is showing response Code "503" for RUM events ( (/intake/v2/rum/events) whenever we are seeing "Queue is Full" message in APM Server.
As per our understanding, If the server is not able to process the event it will be lost & not impact the application availability.
Could you please help to address the issue.
