System Reboots while large file writes after Cobia upgrade

[tws101]

System is a
TRUENAS-MINI-3.0-XL+

2 vdev
3 disk Z1
3 disk Z1
+2 Hot Spares

Large file writes usually by PC backup software causes a system reboot... This can be reproduced by writing a 50 Gig file or large and the system will fail and reboot 70% of the time.......

Disk activity shows about 100 mbits per second across all 6 disks writing VERY FAST, way faster than Bluefin did... sadly the crash occurs...

I have access to all the logs what would I need to look for to figure this out?

Also other than turning on synchronous writes which takes speed down by about 90%.. what other setting can be used to slow it down a little bit?

A bug ticket with debug file attached should give us all the logs we need to see if there's a software issue here, or else if its something HW related. Instantaneous reboots can be heat related though as well, might be worth checking to make sure the unit is clean and airflow is good.
