Slapd Error Handling Problem


After a month in production, we now had the first real problem
with a corrupted attribute index file. Openldap version is 1.2.6 running
on linux 2.2.10, using BerkleyDB 2:

conn=157146 op=1 SRCH base="DC=MAIN-RHEINER,DC=DE" scope=2
ldbm_db_errcall(): ==> /usr/local/slapd-web1/data/back-ldbm/mail.dbb:
page 1078871380 doesn't exist, create flag not set
conn=157146 op=1 RESULT err=0 tag=101 nentries=0
conn=157146 op=-1 fd=21 closed errno=0

What I am really concerned about is not the ldbm error, since
we are able to rebuild the database using ldif backups.
Slapd sends an LDAP_SUCCESS instead of eg LDAP_OPERATIONAL_ERROR back
to the client. As a result of this, all email for the above user bounced
with a 'User unknown` error. This behaviour is simply not acceptable
since it directly affects quality of service for our users.

Is this problem known or fixed in 1.2.7 ? I will soon upgrade to 1.2.7
since it fixes many other open issues. Meanwhile I will have a look
at slap/search.c and slapd/back-ldbm/search.c.
