Kernel Panics w/ Telegraf (bad register)

Dear InfluxData Community,

Over the past several weeks, we’ve seen weekly kernel panics on some of our production instances (Ubuntu 18.04, kernel 4.15 - 4.18); while those instances are massive & running several hundred processes, in all cases telegraf is part of the kernel stack trace. Have you ever seen this anywhere?
