I'm trying to inster in my directory (with ldapadd)
the following entry with a pretty big multivalued attribute:

dn: cn=Member,ou=roles,o=fc-sante
objectClass: top
objectClass: groupOfUniqueNames
cn: Member
uniqueMember: uid=usertest,ou=People,o=fc-sante
uniqueMember: uid=webmaster, ou=People , o=fc-sante
... 7650 other uniqueMember here ...
uniqueMember: uid=nescoriguel, ou=People , o=fc-sante

ldapadd -v says:

ldap_initialize( <DEFAULT> )
add objectClass:
        top
        groupOfUniqueNames
add cn:
        Member
add uniqueMember:
        uid=usertest,ou=People,o=fc-sante
        uid=webmaster, ou=People , o=fc-sante
... 7650 uid ...
        uid=nescoriguel, ou=People , o=fc-sante
adding new entry "cn=Member,ou=roles,o=fc-sante"
ldap_add: Can't contact LDAP server
ldif_record() = 81


And nothing is added to LDAP.


If I start slapd with -d 255, I get this:

Any ideas where the problem comes from ?
If I cut down on the size, using 2000 uniqueMember works.

Thanks,
