slapcat ldif backup

FreeBSD 10.1-RELEASE

I reported this problem before. I am experiencing periodic backup failure
with slapcat. I run it from CRON if that makes any difference.

This is the exact failure message:

5471c421 mdb_db_open: database "dc=seibercom,dc=net" cannot be opened: No such file or directory (2). Restore from backup!
5471c421 backend_startup_one (type=mdb, suffix="dc=seibercom,dc=net"): bi_db_open failed! (2)
slap_startup failed
LDIF Backup Failed
Exit Code: 0

I ran the slapcat command under "truss" and this is the output:
