Full_Name: Marco Pizzoli Version: 2.4.30 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (213.174.164.11) Hi, I'm facing crashes with openldap 2.4.30 (actually the RE24 of the day before the release, but nothing changed in the meantime). I have a consumer starting from scratch with an empty db. During his starting he populates his db by connecting to 4 servers which are part of a 4-way multi-master cluster. They are running a previous version of OpenLDAP. We are doing an upgrade of our deployment just to solve an issue we face from time to time consisting in data corruption. This bug, which is not the target of this ITS, is able to trigger a crash of the slave slapd 2.4.30. During the first synchronization the consumer is receiving the entire db and I can see on this slave, in the logs, coming two odd entries, like this one: ldap15.log:Feb 28 15:45:02 ldap15 slapd[5219]: conn=-1 op=0: memberof_value_modify DN="p?v#007" add memberOf="cn=mynetbk,ou=allnetbk,ou=systems,ou=mygroups,dc=my_dc1,dc=my_dc2.it" failed err=32 and after that slapd crashes. I produced a core dump and generated the full back trace. And I can see this is due to slapo-memberof. This is my memberof configuration: overlay memberof memberof-group-oc groupOfNames memberof-member-ad member memberof-memberof-ad memberOf memberof-dn cn=Manager,dc=my_dc1,dc=my_dc2.it memberof-dangling ignore memberof-dangling-error 80 memberof-refint FALSE Here is the output. As I said, this output is taken from a slapd 2.4.30. The platform is Linux x86_64.
