Thank you for your shared experience, @blokeman! Yes, this is most probably the reason for my crashes as well because, since my last post, I was able to successfully run models with 15000 iterations but never with 20000 iterations. I guess the memory limit is somewhere in between. Also, I realized that more iterations won’t solve my original problem of the Bayes factor’s unusually high variability, as suggested in this discussion.
