MCMC Multi-Core seems to keep the process in the background alive

Post by aliakhavan89 »

I've been running some experiments using the CMD script (viewtopic.php?t=8538) and the model (viewtopic.php?t=8526) I've shared recently. I noticed that on Vensim multi-core, MCMC gets stuck entirely randomly on different datasets without any freeze or crash:

Apparently, the process still remains alive in the background, and I found it totally by chance when I was getting unusual crash incidents (I think it's happened twice, and that's why there are two left in the background):

This issue was fixed as soon as I started running MCMC on Single-Core. No DLL is used at all.
