Berkeley DB Woes

After updating glibc on my Fedora 27 server this morning, my regularly-scheduled backup of my OpenLDAP-based contacts database started failing: 

# slapcat > backup.ldif
5a4ce631 bdb(dc=city-fan,dc=org): BDB1539 Build signature doesn't match environment
5a4ce631 bdb_db_open: database "dc=city-fan,dc=org" cannot be opened, err -30969. Restore from backup!
5a4ce631 backend_startup_one (type=bdb, suffix="dc=city-fan,dc=org"): bi_db_open failed! (-30969)
slap_startup failed

Although I do have backups I could restore from, it turned out not to be necessary: simply restarting slapd was sufficient: 

# systemctl restart slapd
# systemctl status slapd
