That looks like a forked dhcpcd process may have crashed. Assuming you don't already have a dhcpcd.core somewhere from a non-suid process, try sysctl.kern.nosuidcoredump=2, mkdir /var/crash/dhcpcd, and see if a $PID.core shows up there. You may need to build dhcpcd with debug symbols to get a useful backtrace, see https://www.openbsd.org/faq/ports/ports.html#Backtrace It's probably better to follow-up on ports@ than misc.
