After I import about 1400 accounts to a new database (ebiRoot, People
subtree), I get lot of errors when I run verify-db.pl (slapd has been stopped):
Verify log files in db ... Good
Verify db/ebiRoot/uid.db4 ... Good
Verify db/ebiRoot/mail.db4 ...
DB ERROR: db_verify: Page 37: out-of-order key at entry 247
DB ERROR: db_verify: Page 37: out-of-order key at entry 503
...
Same error for ancestorid.db4, objectclass.db4, parentid.db4, cn.db4,
givenName.db4 and sn.db4.
I have run db2index and re-run verify-db.pl but I don't see any
difference. Here is what db2index says about ebiRoot:
[29/Mar/2007:12:04:26 +0100] upgrade DB - ebiRoot: Start upgradedb.

1424 entries in 3 seconds. (474.67 entries/sec)
Does that WARNING "No other process is alloed to access the database" mean
something is wrong?
How can I locate those "out-of order keys" the db_verify lists? I tried
with dbscan but I don't think I'm giving the right entry id:
$ ./dbscan -K 247 -f db/ebiRoot/mail.db4
Can't set cursor to returned item: DB_NOTFOUND: No matching key/data pair found
Is there a way to find out which entries are causing the problem? Can
there be illegal characters in the entries?
If I import a considerably smaller set of entries (120), I get no errors.
I noticed there was a similar thread here but no conclusion:

Sorry for so many questions, I've spent couple of days trying to
solve the problem.
If I delete a database with the Console, it leaves behind couple of index files:
-rw------- 1 w3secure systems 16384 Mar 28 17:05 ancestorid.db4
-rw------- 1 w3secure systems 18 Mar 28 17:03 DBVERSION
-rw------- 1 w3secure systems 32768 Mar 28 17:05 id2entry.db4
These index files don't seem to shrink when new entries are imported.
dbscan still shows the deleted entries in id2entry.
I noticed a problem when I import a small set of entries, delete the
database, import large set of entries and if I query the entries, I get
the entries from the first set (they don't exist in the second set). I can
reproduce the problem. If I delete ancestorid.db4 and id2entry.db4
manually when I delete the database, I don't have this problem. Is there a
reason why those two files are not deleted? Or can this whole thing be
caused by corrupted data?
