Package: slapd
Version: 2.4.31+really2.4.40-3~bpo70+1
There is an openldap instance with mdb backend. Modifying 40k entry,
more specifically delete an attribute from each entry causes the MDB
database to be filled up.
Freshly created backend database, after slapdadd the data.mdb is around
250 MB.
olcDbMaxSize: 1024000000 (1 GiB)
While running the ldapmodify, after some time
"ldap_modify: Other (e.g., implementation specific) error (80)
additional info: commit failed
"
error produced. After restarting slapd
"ldap_modify: Other (e.g., implementation specific) error (80)
additional info: entry update failed
"
data.mdb became 977 MB
slapd log the following to syslog:

As mdb_stat states 750 MB of the 1GB is free, so I believe this is not
the expected behavior.
Any idea?

Yes, I messed up with the first testing. I could not reproduce the
problem with 2.4.40 only with 2.4.31 and 2.4.39
OK, marking as fixed in 2.4.40.
Knowing this I think there is no point in asking it on
openldap-technical, as their opinion is usually use the lastest stable.
In the case of back-mdb, I have to agree that a recent release seems to
be necessary for stable operation.
