I run slapd  from a long time on FreeBSD stable amd64 and it is started with
args:

  slapd -4 -h "ldapi://%2fvar%2frun%2fslapd.socket ldap://localhost/
ldap://ldap2/ ldaps://ldap2/"  -u ldap -g ldap

After upgrade from 2.4.30 to 2.4.31 my server can't start:
slapd[29221]: read_config: no serverID / URL match found. Check slapd -h
arguments.
Nothing was change in en environment - only ldap was upgraded.

After backing-off only this one commit to bconfg.c:
  http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=commitdiff;h=b4d403ea310022ca4ffcbf31fa20ead6c754f28d

all is working again.
Any clue ?
and IHMO this message shod be more informative for casual user.
