How to limit the memory usage of a VB.NET process in Win Server 2008
Hi there. I currently host a website with a VPS (Virtual Private Server) which only has 1GB RAM. This limited memory is generally ok, however I need to run an console application (written in VB.NET) which can run at quite a high memory usage.
I don't need the console application to run fast... just to run all the way through without dying prematurely, having reached the machine's RAM limit.
As the server is a VPS I don't think I can make use of hard drive space to substitute for RAM (page file).
Instead, I'm hoping there is a way to limit the amout of RAM that the process uses, either through a Windows Server 2008 setting or somehow through the VB.NET code that the console application is written in.
Any advice greatly appreciated.

The problem is that it is running on VPS Container that shutsdown Services when the memory spike above the amount allocated to the VPS, even if the amount is not correct.

I said declaring now objects... meant to say declaring new objects...
As ICaldwell mentioned, there really isn't much an application can do to influence it's memory usage. In Windows physical memory is completely managed by the system, not the application. Task Manager does not show this but RAM will be used to the fullest possible extent, no matter how much or little might be running. Free memory is a great evil in a modern OS. Memory is dynamically assigned to running processes according to their needs and RAM availability. Like RAM, the pagefile is managed by the system and cannot be used directly by applications. What Task Manager shows as "Available" memory DOES NOT impose a limit on what applications may still be run, only on how well they will perform. Your console app should run, even if available memory is low. If necessary, the system will take memory from other processes to meet it's needs. This is a routine and completely normal situation.

Thanks ICaldwell and others that commented
Here is an article on it: http://www.itwriting.com/dotnetmem.php
Basically there is not much you can do about it... If you create applications in native C++ then you can use the memory tab in task manager to monitor the memory usage...
