Hi Ben,

First, I noticed that syslogd wasn't running on your machine.  So I went
to start it, but found that FreeBSD uses some unique (nonstandard)
setup.   We do not yet support FreeBSD (but we're working on it), so I'm
not yet sure how syslogd should be set up.  But, my co-worker has some
experience with FreeBSD.  From him I found out that the best interim
solution is to use the -l <logfile> option to the LDM programs.  This is
what I would suggest for you for now so that logging works properly.

Tomorrow, I will continue on this further.  I'll identify places to add
the -l option, and take a look at the pqact.conf entries.  And, I see
that your latencies are bad.  I'll take a look at that too.

Did I hear your oyster joke and just forget it?  Oldtimers disease is
such a blessing - everything's always fresh and new!

Anne
