Hi,
I'm running relayd/OpenBSD 5.6-stable on a KVM virtual machine. relayd
always crashes within a few hours of restarting it, but works properly
before that.
When relayd stops working, sometimes the relayd process is up but
`relayctl show summary` says that /var/run/relayd.sock doesn't exist.
Other times none of the relayd processes are running.
Here's some info:
$ uname -a
