Excessive RAM Usage while using parsim

​When I try to run my model using parsim on Matlab 2021b Update 8, the RAM usage of client (where parsim is executed) increases up to ~50 GB while the model is running but the RAM usage of the workers remains normal. When the simulations are done, the usage decreases. Here are main things to state: ​1) Model is running in rapid accelerator mode and built in a distinct folder before parsim is evaluated. ​Each worker is configured in setupfcn to use the pre-built model in the folder. ​ 2) Copy workspace option of parsim is turned off but I save and load needed variables in each worker using setupfcn. However, large variables such as simulation input variable are not saved to minimize RAM use. ​ 3) My simulation input object is about 700 MB. ​4) My PC has 10 cores and 64 GB of RAM. ​I use 8-10 workers but the problem continues even if I use fewer workers. ​ 5) InspectLogging configuration is turned off. ​ShowSimulationManager is turned off. ​Simulink.sdi.setArchiveRunLimit(0); Simulink.sdi.setAutoArchiveMode(false); are included in startup script. ​ 6) I have logsout object and I use it in postSimFcn but I return out = Simulink.SimulationOutput(); at the end of the postSimFcn. In addition, I am sure that the returned output objects of parsim are just empty. ​What could be the reason for this problem? I think the problem is related to SDI as the RAM usage increases while running but I couldn't find any other way to solve it.
