When a shortdump associated to the Redpeaks user is discovered in the system, it is because of a remote function call which ended badly.
To resolve the problem, you need to identify what Function Module or what Report was executed.
For that, you need to correlate timestamps of the shortdump with what was executed at this exact same moment in Redpeaks, to discover which monitor is the responsible.
The best way to do that is by checking the logs.
Only one monitor at a time is executed on a system. If a shortdump occurred at 2h 42m 25s, check which monitor was executed in last just before this time.
Usually, you should see an exception in the logs giving more info about the reason.
In many cases, the monitor can also simply time out and get killed, forcing the connection to close.
