frequent crashes when using two monitors

I'm dealing with a strange problem with Final Cut Pro X 10.2.1 on a 2013 Mac Pro with two Dell monitors connected via DVI to Mini Display adapters.

When running FCPX on both monitors (using the second monitor for Events) the application will crash very frequently, sometimes every few minutes. When I switch back to using only one monitor for Final Cut, things are much more stable.

Curiously, we have other systems that use Apple Thunderbolt Displays and they do not seem to have this dual screen crash bug. Is there something about using non-Thunderbolt monitors that would cause this behavior? We are working around the issue by keeping FCPX on one display, but I would like to get this figured out. Thanks!

You should start by making sure the two monitors are attached to different thunderbot buses. The six ports on the MP are on three different buses:

Use multiple displays with your Mac Pro (Late 2013) - Apple Support

Delete preferences, as they often get corrupted after a crash, and try again.

Thanks for the reply. Putting the monitors on different buses is tricky because we have a fibre channel adapter and an AJA Io 4K connected to the other two.

Agreed with Luis, I have 2 Samsung 4k monitors running into 2 of the thunderbolt ports and 2 x 4 port thunderbolt splitters to the hard drives. This works for me and the monitors never crash but sometimes the second one goes offline for a second. A few times the monitors have reversed and I have to reset them in FCP X. Hope this helps and best wishes.
