Remove limit of RAM memory usage

[Nikita Lavrenko]

Hi there. I'm faced with problem of limits for usage RAM. 

I have 128GB RAM but I see that MT5 has a limit: 14.5GB for one processor thread and all remaind required memory loads into disk, but disk space isn't enough.

Please, help me to unlock this limit, I want and to use my RAM more than 14.5Gb for the thread.

If this is'n a bug, please, give some guide how to change this limit. 

Screenshot attached. 

Thank you!
