Can anyone help me work out why my iMac keeps restarting. It's a fresh install of Mojave as i was encountering the same problem with Catalina.
It only restarts when I try to launch dropbox and it just crashed when I tried to run Rember memory test as i suspected the problem might be ram. I have just purchased the 2019 27" iMac from Ebay.

There is not much in the kernel panic report. A "kernel trap, type page fault" can often times be anything.
The #2 cause of kernel panics is 3rd party RAM, and you have two 32GB DIMMs and two 16GB DIMMs which tells me you have 3rd party RAM.
This is a weak association, so take this for what it is worth.
You can try running Rember

.
Quit as many apps and background tasks as you can (such as menu bar items) so more RAM is available for testing. Booting into Safe mode http://support.apple.com/kb/ht1564 can also free up more RAM for testing, by not loading any 3rd party additions you may have installed.
.
Set Loops: [X] Maximum
and run overnight
If it does find something, then you can contact your RAM vendor and ask for replacement.
BUT IF Rember DOES NOT find anything, it just means Rember did NOT tickle the RAM in such a way that caused it to misbehave, or because the RAM is good. Basically a negative result proves nothing.
