Hi all, First, thank you for the conversation around this.

I'm using *dynamic-place*, which clearly is why I'm running into limits. Unless anyone has alternative ideas, I'm going to restructure my code to use distributed places on the single machine, which will, I think, give me multicore parallelism and eliminate the file descriptor limit I'm running up against. Many thanks, again. I locked in my head I was using distributed places, and was blind to my own code. I've kept the test case I wrote, below, that let me see clearly what I was doing, as opposed to getting caught up in all the other things my code was engaged in. I'll leave it below for posterity's sake, but it doesn't serve a particular role at this point. Cheers, Matt --- NOT QUITE RELEVANT ANYMORE... I've written a small test case, and with Stefan's suggestion, dropped the soft limit on descriptors to 100. I can run my test case with 100 distributed places when the soft limit is 1024 (and I end up with 708 descriptors in use when all of the distributed places are idling), and it crashes immediately/very quickly when I drop down to 100 descriptors.
