Memory problem 2.4.17-2.1~bpo50+1
Hello,
Every night I dump the LDAP data in a ldif file. I do this for years and
on several servers. Since the last upgrade van LDAP (slapd, ldap-utils,
libldap-2.4-2) to version 2.4.17-2.1~bpo50+1 the dump fails with serious
memory errors. As far as I can see it has nothing to do with the content
of the LDAP.
Command executed
/usr/sbin/slapcat -c -b "dc=example,dc=com"
