How to limit usage of virtual memory by node.js?

I am working in an embedded environment, where resources are quite limited. We are trying to use node.js, which works well, but typically consumes about 60 megabytes of virtual memory (real memory used is about 5 megabytes.) Given our constraints, this is too much virtual memory; we can only afford to allow node.js to use about 30 megabytes of VM, at most.

There are several command-line options for node.js, such as "--max_old_space_size", "--max_executable_size", and "--max_new_space_size", but after experimentation, I find that these all control real memory usage, not maximum virtual memory size.

If it matters, I am working in a ubuntu linux variant on an ARM architecture.

Is there any option or setting that will allow one to set the maximum amount of virtual memory that a node.js process is allowed to use?

You can use softlimit to execute the node with limited size. Or you can directly use setrlimit of Linux, but not really sure how to call it from NodeJS, see this SO question
