I have a number of Supermicro servers and a number of them unexpectedly reboot every 5-15 days, seemingly at random. The machines each have 96GB of ram
I have only managed to catch a complete crash message once, and a few partials:

The problem seems to be with the igb(4) driver. I have repartitioned the Whiskey machine with a 100gb dump device in hopes of capturing a proper crash dump.

>How-To-Repeat:
Use igb(4) based NIC on various SuperMicro motherboards, after a while kernel will panic. Servers are under different levels of load, no real indication of a 'trigger'
