Have you been suspending the host system? Vito and i noticed oddities in the vm when we suspended our gentoo hosts with a coreos vm in qemu running. On Nov 24, 2015 1:54 PM, "Jonathan Boulle" notifications@github.com wrote:
Noticed on qemu-x86_64, CoreOS 845.0.0. As far as I'm aware the system was basically idling at the time this happened, and it's still up (8 days total)

https://github.com/systemd/systemd/pull/1783 is one I fixed which triggered via suspending the host for long periods, but the issues in this ticket look different, looks like the guest's kernel is getting balled up in rcu land over timekeeping
The systemd daemons have watchdogs which will trigger coredumps on expiration, which may be what's causing the coredumps above, and the root cause could just be suspend/resume-induced time shifts.
They increased the timeouts recently because journald was apparently getting false-positives on the watchdog expiration due to IO latency: https://github.com/systemd/systemd/commit/c2fc2c2560f0ca0fab383753c065e45d76f465e5 and http://github.com/systemd/systemd/issues/1353
I haven't dug into this, but from a casual/speculative perspective thinking about it:
Maybe the watchdog needs to defer dropping the hammer to see if the time is jumping.
one of coreos users has probably similar problem (CoreOS-stable-766.3.0-hvm (ami-f396fa96)):

He also has coredumps:

I'm closing this due to inactivity, please reopen if more journald errors like this emerge, we've fixed a number of things which might have resulted in such crashes.
Noticed on qemu-x86_64, CoreOS 845.0.0. As far as I'm aware the system was basically idling at the time this happened, and it's still up (8 days total)
