https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235856 --- Comment #8 from Charles O'Donnell <cao@bus.net> --- Same symptoms still occurring regularly here. Begins with "nvmeX: Missing interrupt" in the logs, which can go on for a few hours, then the server becomes unresponsive. Typically occurs 4-6 days after boot. Only the most heavily loaded production servers are affected. Other servers have never exhibited this behavior. Have tried a variety of instance types. At this po= int I have it monitored so I can do a graceful cycle before it locks up.=20 See also bug #236989 Uname: FreeBSD 12.0-RELEASE-p10 FreeBSD 12.0-RELEASE-p10 GENERIC amd64 Log excerpt: Aug 27 03:02:45 host kernel: nvme4: Missing interrupt Aug 27 03:02:56 host kernel: nvme1: Missing interrupt Aug 27 04:19:11 host kernel: nvme1: nvme4: Missing interrupt Aug 27 04:19:11 host kernel: Missing interrupt Aug 27 04:19:30 host kernel: nvme0: Missing interrupt Aug 27 05:16:58 host kernel: nvme1: Missing interrupt Aug 27 05:16:58 host kernel: nvme4: Missing interrupt Aug 27 14:58:13 host kernel: ena0: Keep alive watchdog timeout.
