Hi Martin,
Thanks for the feedback. I’m pretty sure it is a RAM issue as well as browser. The memory limits kill the kernel but I was also have a stall out of the Safari browser, which would then kill and refresh the Jupyter Notebook visuals. Seems to have resolved with Firefox.
No reason specifically on the 10K draws. On some test data that were mixed (e.g. some missing phases, different number of regions, etc.) I had some ESS warnings, so thought I would boost the total number of draws.
