    Fixing logger solved this issue. Load has dropped from 6-8 to 1-2 (on a 2-proc system). Thanks to all for the good advice in this thread.

    Thanks y@w! That worked, the table is repaired and the error log is quiet. Now it's just a matter of watching iostat and system load. Hopefully I'm approaching a solution.

    Maybe it's a LVM Snapshot problem

    bacula-fd runs as a daemon, but the backup job happens only at night, so I *think* this is safe. And yes, to answer your question, bacula-fd has been running ever since the machine was last booted...

    use the LDAP query from postfix

    Anyone know how Zimbra's postfix queries LDAP when looking up valid email addresses? This would probably be the same query I need to run from the edge MTA.

    Any pointers?
