I'm using f28 cloud on AWS as a compute farm. It seems that instances
randomly shutdown within hours of starting. An example log:
...
Fedora 28 (Cloud Edition)
Kernel 4.16.3-301.fc28.x86_64 on an x86_64 (ttyS0)
Stopping Restore /run/initramfs on shutdown...
[[0;32m OK [0m] Removed slice system-sshd\x2dkeygen.slice.
Stopping User Manager for UID 1000...
...
In this case after about 4 hours it seems to have spontaneously shutdown.
This happens with high probability - maybe 2/10 instances I start
spontaneously shutdown.
Any ideas what's going on? I'm just wondering if this is something specific
to fedora cloud edition, because it doesn't seem to be a common complaint on
AWS (most of which is ubuntu).
