Checking on a system where dhcpcd has exited - there does not appear
to be any files in /var/run/dhcpcd - though there are two directories
and a selection of files in /var/db/dhcpcd, including lease files for
interfaces not in this system (software and hardware have been
upgraded a number of times).

I've saved a copy of them, then "rm -rf /var/run/dhcpcd
/var/db/dhcpcd" and restarted dhcpcd

Will check back in a few days to see if the issue reoccurs.

Thanks
