Question

I am getting an error while calling MCR through my .NET application that "could not start JVM because of low virtual memory","Could not reserve enough space for object heap". I have MCR 7.16

Thanks In advance.

Hi,

This is basically an out of memory error thrown by the JVM. You can either lower the heap space of the JVM, or move to a 64bit System with enough RAM.

For lowering the heap space see here:

put that java.opts in:

Or if you don't use any graphic on the MATLAB side, consider disabling the JVM completly:
