@anodos The test I was doing that was causing the crashes was taking 200 GB + transfers of lots of movies (about 10 movies and lots of Movie Extras files). Many of the movies were 15 GB or more in size. This problem was occurring on multiple Mac computers (all running Mojave 10.14.4). Since I changed out every piece of hardware of the FreeNAS and it's happening on multiple Apple machines- it leaves me to believe it's FreeNAS software related. Now that I'm 11.1-U5, I am no longer getting any dropouts as well as no random reboots. I just ordered all new hardware to build a second FreeNAS, so I'll be able to do further testing in a few weeks with a completely new build from scratch.
