We have an 64-bit application that runs in c++ code in 16gb ram windows virtual machine. After few days of running the application,whole Pagefile.sys memory(32 GB) got filed and leads to crash.In resource monitor

If it is memory leak why it doesn't showing growth in Working set memory ? I would also like to know in what situations, only commit memory will grow greater than working set memory? What tools for c++ we can use to identify the root cause for this problem?
I understand that commit size includes RAM used and Virtual memory. please explain why virtual memory used not able to deallocate even process in idle state?
Note:-In this application no virtualAlloc() has used only c++ new operator has been used.
