Oh yeah!  Now I remember.  Between us we must know all the oyster

Morning Ben,

First, to get logging working better on your FreeBSD system, I suggest
adding -l /project/ldm/logs/ldmd.log to calls to LDM programs where you
can.  Specifically in ldmd.conf make this change: 
                exec "pqbinstats -l /project/ldm/logs/ldmd.log"
                exec "pqact -l /project/ldm/logs/ldmd.log"

and in ldmadmin, change this line in start_ldm:
 
    $cmd_line .= " -q $pq_path $ldmd_conf > $pid_file";
to:
 
    $cmd_line .= " -l /project/ldm/logs/ldmd.log -q $pq_path $ldmd_conf
> $pid_file";

(You'll have to remember to migrate this change to your new ldmadmin
when you upgrade.)

Then restart the LDM for the changes to take effect.


Second, here's a problem in pqact.conf:

(anvil.eas.purdue.edu) [/project/ldm/etc]% ldmadmin pqactcheck
Aug 16 17:25:40 pqact[55175]: Syntax error at line 302, not enough
fields

The problem is that the third line does not start with a tab.  To
confirm this, I place a tab at the beginning of the line, and ran
ldmadmn pqactcheck again.  It reported back that there was an error 4
lines later, the next place where a tab is required.  I made that change
and tested it again.  I'll leave the rest of the changes for you to
make.

Once these changes are made I believe pnga2area will log to
/project/ldm/logs/png.log as it is supposed to from the pqact.conf
entries.  I just tested running pnga2area from the command line again
using the -l /project/ldm/logs/png.log and logging worked fine.  If you
look in that log now you'll see the error messages that I just sent to
Tom in my previous email.

So, please make the above changes, and we'll proceed from there with
problems pnga2area is having, and the latency issue.

Anne
