I am getting this error after (re)booting, if I restart slapd it is
gone. I guess I can ignore this message because slapd will recover from
this eventually? Or do I need to give it a restart every time?


After reboot:

It means:

a) You're using shared memory regions with a BDB backend
b) That slapd is not cleanly shut down on a reboot. It sounds like perhaps you have a broken init system.
I would note that BDB based backends are deprecated. It's advised to use back-mdb instead.
