Simulation stuck after 2048 users in the network #180

Describe the bug I am running a simulation in omnet++ 6.0pre11 with Simu5G-1.2.0 and inet4.3

I am creating users dynamically during the simulation i.e. Adding nodes to the system and removing the nodes to the system.

The simulation runs successfully till 96% and then remains stuck. This happens when we have more than 2048 connections in the network. The simulator does not throw anykind of error or result in simulation failure.

When I check the status in linux server, omnet process occupies 100% of the CPU usage. I am running on the server which has 48 cores and omnet is utilising just 3 cores. So there is no cpu constraint.

Can anyone point to a potential way to debug the simulator?
