Investigating. Found this on Orfeo:

Oct 30 03:18:32 Orfeo postfix/trivial-rewrite[26740]: fatal: ldap:/etc/postfix/ldap_virtual_domains.cf(0,lock|fold_fix): table lookup problem

and on Toushirou (Elwing logs have been ignored, due to ADSL disconnections; also see #173):

Oct 27 04:33:13 Toushirou slapd[20484]: do_syncrep2: rid=002 (-1) Can't contact LDAP server
Oct 27 04:33:13 Toushirou slapd[20484]: do_syncrepl: rid=002 rc -1 retrying (2 retries left)

If the syncrep problems may have been caused by connectivity problems (#148), the postfix one is a real one to fix.

Checked crontabs, but found no problem. srv_backup_databases is not stopping the LDAP server, and srv_dspam_daily_maintenance does not touch services anymore.

The timing also match the backup, to i moved 2 crontab entries out of the time range in order to disculp them and perhaps improve the situation. I can't find a way to nice or limit CPU on the bacula fd.
