Just as a followup from having the issue now - I force killed and restarted the process as it wouldn't shutdown normally - it came up with:

slapd[12047]: @(#) $OpenLDAP: slapd (Feb 27 2014 09:38:39) $#012#011root@debian: slapd[12048]: hdb_db_open: database "dc=test,dc=com": unclean shutdown detected; attempting recovery. slapd[12048]: slapd starting slapd[12048]: => bdb_idl_delete_key: c_get failed: DB_LOCK_DEADLOCK: Locker killed to resolve a deadlock (-30994) slapd[12048]: conn=-1 op=0: attribute "entryCSN" index delete failure

Hi all,

I'm running 2.4.39 with Mirrormode replication. I've noticed that occasionally when making schema changes, a change will hang indefinitely without reason. Though (possibly as a cause), also I've found that if I try and restart one of the three servers in this replica set, it will occasionally get the following with causes it to hang indefinitely:

Oct 1 08:55:37 ldap-03 slapd[19608]: daemon: shutdown requested and initiated. Oct 1 08:55:37 ldap-03 slapd[19608]: slapd shutdown: waiting for 2 operations/tasks to finish

The other hosts show the disconnection and try and reconnect - the only way to fix it seems to be either force killing this server or restarting all the other hosts.

Any ideas? It's a fairly standard setup with mirrormode as per the doc's.

I've seen there is 2.4.40 released however haven't scheduled in an upgrade yet as there wasn't anything on the changelog that appeared to be linked.

Cheers
