The /usr/local/etc/rc.d/couchdb3 file has an error in the path in the start section

This

HOME=/var/run/couchdb \
ERL_CRASH_DUMP=/var/run/couchdb/erl_crash.dump \

must be:

HOME=/var/run/couchdb3 \
ERL_CRASH_DUMP=/var/run/couchdb3/erl_crash.dump \


The complete start section is:

couchdb3_start()
{
    # chdir manually as overriding _start() blocks rc.subr defaults
    cd "${couchdb3_chdir}"
    /usr/sbin/daemon -p ${pidfile} \
