I'm sorry, but knowing that a single process is showing high virtual memory utilization and is showing comparatively lesser virtual memory consumption seems to imply that two people looking at the same process see it's memory consumption differently. My crystal ball isn't seeing anything obvious to suggest which observer might be correct (if either observer is correct), nor is it able to suggest what to investigate to substantiate either claim.
If we could see the code, we might be able to suggest conditions under which it might use a lot of memory.
If we can't see the code, we can make a lot of assumptions that might or might not apply to some process no matter what language is used to write that process? If we can't see the code, can't see anything other than a conflicting statement about memory usage, and have no idea what the process is doing; there is absolutely no way that tell you what, if anything, is wrong with your code.

mlockall
mlockall(2) System Calls Manual mlockall(2)
NAME
mlockall() - lock a process virtual address space in memory
SYNOPSIS
DESCRIPTION
The system call allows the calling process to lock its entire virtual address space into memory, making it immune to all routine swapping.
flags may be one or both of the following:
Lock the current process virtual address space.
All addressable pages of the address space are locked.
Lock any future additions to the process virtual address space.
Note that does not imply
or can be used to unlock all or a portion of the address space locked with A single call to removes all locks from the process virtual
address space. An call results in only the specified pages being unlocked.
Regardless of how many times a process locks a page, a single or will unlock it.
When memory is shared by multiple processes and mlocks are applied to the same physical page by multiple processes, a page remains locked
until the last lock is removed from that page.
Locks and applied with are not inherited by a child process.
The user must have the privilege.
Although and the family of functions may be used together in an application, each may affect the other in unexpected ways. This practice
is not recommended.
Security Restrictions
Some or all of the actions associated with this system call require the privilege. Processes owned by the superuser have this privilege.
Processes owned by other users may have this privilege, depending on system configuration. See privileges(5) for more information about
privileged access on systems that support fine-grained privileges.
RETURN VALUE
returns the following values:
Successful completion.
Failure.
The requested operation is not performed. is set to indicate the error.
ERRORS
If fails, is set to one of the following values:
The flags field did not contain either and/or
There is not enough lockable memory in the system
to satisfy the locking request.
The user does not have the
privilege.
EXAMPLES
The following call to locks the entire process virtual address space in memory and ensures that any future additions to the address space
will also be locked in memory:
