Hi,

We just suffered from the same issue. This particular FreeBSD 12.1 r5.large
instance with an additional gp2 disk (ZFS)  was up for about 2 weeks when this
occured.

These are the last entries in the "logs" :

Nov 25 03:04:36 zfs01 kernel: nvme1: cpl does not map to outstanding cmd
Nov 25 03:04:36 zfs01 kernel: cdw0:00000000 sqhd:001a sqid:0001 cid:0018
p:0 sc:00 sct:0 m:0 dnr:0
Nov 25 03:04:36 zfs01 kernel: nvme1: Missing interrupt
Nov 25 03:04:36 zfs01 kernel: nvme1: Resetting controller due to a timeout.
Nov 25 03:04:36 zfs01 kernel: nvme1: resetting controller

Nov 25 03:05:37 zfs01 syslogd: last message repeated 4 times
Nov 25 03:06:07 zfs01 kernel: nvme1: Missing interrupt
Nov 25 03:09:08 zfs01 dhclient[84191]: send_packet: Host is down
Nov 25 03:09:52 zfs01 syslogd: last message repeated 4 times

@Colin/@Alex: Do you know if this occurs on "older" instance types as well? We
would definately switch to older instance-types if this issue doesn't occur on
older generations.

Kind regards,

Ruben
