General R troubleshooting:
What does executing Cstack_info() after you get the exception tell you?
Are you using 32 bit R and how big are your datasets?
If so, have you tried 64 bit R?
R.Net troubleshooting:
Are you disposing of the datatypes that are returned when you are done with them? (Not the rengine?)
Is there a way to map less types to C# types and do more inside of evaluate?
Similarly, could you just read the R console to get the values you want (as strings, instead of disposable C#/R types)?
