[Pkg-openldap-devel] Bug#471253: slapd hangs and eats 100%cpu with syncrepl statements

[Mathieu Parent]

Package: slapd
Version: 2.4.7-5
Severity: critical

--- Please enter the report below this line. ---

When using the following config file (reduced testcase or full), 
and running a quick and dirty test(be carefull, it clean all slapd data) :

/etc/init.d/slapd stop
rm /var/lib/ldap/*

/usr/sbin/slapd -h ldap://127.0.0.1:389/ -f /etc/ldap/slapd.conf \
-u openldap -g openldap

cat <<EOF | ldapadd -D "cn=manager,cn=internal,dc=sathieu,dc=net" -w 12345 -x
dn: dc=sathieu,dc=net
dc: sathieu
objectClass: top
objectClass: domain
EOF

It hangs, and slapd eats 100% cpu. I have to do:
  killall -KILL slapd
because ''killall slapd'' doesn't work.

I simply want this to resturn somehing:
ldapsearch -D "cn=manager,cn=internal,dc=sathieu,dc=net" \
  -w 12345 -x -b "dc=sathieu,dc=net"


Can somebody reproduce this ? Can I provide more informations ?


Thanks

Mathieu Parent

NB: this file is for the future kolabd 2.2 package. We need syncrepl for lenny.
