Question: "stack limit reached" when using Grid:-Map

Question:"stack limit reached" when using Grid:-Map

Hi there:

i use Grid:-Map() to run some code on many cores. When I set

Grid:-Setup(numnodes=23);

everything runs fine. When I set (note I have 28 logical cores present):

Grid:-Setup(numnodes=24);

I get the "stack limit reached" message (see attached image below). I've explored setting stack limits to 'unlimited' at the OS level (ubuntu 18.04), as well as setting

kernelopts(stacklimit=infinity)

However, these do not help, and I still end up with the same message.

Any ideas what could be the problem? Also, I am assuming that kernelopts settings get passed to other, spawned kernels, but even if not, I experimented with setting this directly inside the function that gets passed to Grid:-Map()

thanks
