Good to know the problem is fixed. However, I'd advise against using 0 for the memory limit in a production question because a memory gobbling submission might then be able to cripple Jobe. It's safer to find a value at which a typical submission will run OK and then, say, double it. 

I'm also curious as to why your Jobe server seems more prone to memory limit problems than ours. Are you perhaps running it on a 32-bit OS?

I've just been asked for more information about R questions, so I'm posting an XML export of two versions of a very simple R question. One version is like the above, using a customised python3 question. The other version is split into two: a prototype to define a new question type Rtest and the actual question that uses that prototype.

Obviously R needs to be installed on Jobe for either of these questions to run.

Please realise I'm not an R programmer and cannot offer any R-specific support.
